「」の検索 Nickel 201 plate for hot caustic equipment ASTM B162 supplier 通常、これはすでに一般的なニッケル合金に関する問い合わせの段階を過ぎた買い手からのものです。残された作業は、品種の特定、主な損傷メカニズムの特定、図面を注文可能な板材に変換すること、そして購入を正当化するためにどの検査記録が必要かを決定することです。.
The service in this case combines caustic concentration, maximum metal temperature, oxidizing salts, sulfur contamination, plate thickness, forming strain, cleaning, and shutdown deposits. Nickel 201 plate combines commercially pure nickel caustic resistance with a low-carbon basis suited to hotter service than Nickel 200 can normally support. That statement is a selection rationale, not a guarantee of immunity. Low carbon does not make the alloy immune to every caustic process. Temperature, concentration, contaminants, stress, deposits, and cleaning chemistry still define suitability.
For purchasing Nickel 201 plate for hot caustic equipment fabrication, plate projects often fail commercially because the ordered rectangle does not include forming trim, weld preparation, nesting loss, or transport limits. The inquiry therefore needs thickness, width, length, flatness, edge condition, rolling allowance, and final cut plan; it also needs the ordered condition, certificate scope, test requirements, delivery schedule, and destination. When one item is left open, suppliers can quote materially different products under descriptions that look similar.
This guide is written for engineers, fabricators, maintenance teams, and industrial buyers. It explains where Nickel 201 earns its place, where its selection boundary lies, how to specify plate to ASTM B162, and how to review a quotation without confusing a mill certificate with proof of service suitability.

材料の識別、UNS指定、およびASTM規格への準拠
Nickel 201 is identified as UNS N02201 and is the low-carbon commercially pure nickel grade used when caustic resistance and elevated-temperature stability are both important. For this article, the procurement standard is ASTM B162 and the ordered form is plate. The purchase order should repeat all three identity points because commercial grade names, UNS designations, and ASTM form standards serve different purposes.
ASTM compliance controls product requirements within the scope of the standard. It does not, by itself, approve Nickel 201 for hot caustic equipment fabrication, calculate corrosion allowance, qualify a weld procedure, or prove remaining life. Those responsibilities stay with the project specification and design authority. The delivered condition should be stated as solution-annealed condition where required by the governing specification, with the ordered surface and plate identification preserved.

| マンガン | 0.35%（最大） | 製品の品質管理を実施 |
These ranges are a procurement-oriented summary for Nickel 201, not a substitute for the current edition of ASTM B162. Acceptance must use the values required by the purchase order and the actual mill certificate. The buyer should check that heat number, grade, UNS, chemistry, dimensions, condition, and test results all refer to the same delivered plate.
Chemistry explains why Nickel 201 behaves as it does, but microstructure and condition determine how that chemistry arrives in hot caustic equipment fabrication. Heat treatment, cold work, grain structure, surface, and section size can influence response and fabrication. For this plate, do not accept an offer that leaves condition undecided after order placement.
合金冶金学とサービス上の課題を結びつける
The selection case for Nickel 201 plate for hot caustic equipment ASTM B162 supplier rests on several different contributions rather than one headline property. Nickel 201 plate combines commercially pure nickel caustic resistance with a low-carbon basis suited to hotter service than Nickel 200 can normally support. The following points explain how the alloy’s metallurgy connects to the stated service.
多くの苛性アルカリ環境に対して優れた耐性を示す
Nickel 201 offers excellent resistance to many caustic alkali environments. In hot caustic equipment fabrication, this supports the design by addressing part of the combined exposure: caustic concentration, maximum metal temperature, oxidizing salts, sulfur contamination, plate thickness, forming strain, cleaning, and shutdown deposits. This benefit matters only when the process and fabrication assumptions remain valid. The project should identify the exact location where this property is needed and the condition that would invalidate the assumption.
高温環境での使用に適した低炭素含有量
Nickel 201 offers low carbon content for elevated-temperature service. In hot caustic equipment fabrication, this supports the design by addressing part of the combined exposure: caustic concentration, maximum metal temperature, oxidizing salts, sulfur contamination, plate thickness, forming strain, cleaning, and shutdown deposits. The drawing should translate this benefit into geometry, condition, and inspection requirements. The project should identify the exact location where this property is needed and the condition that would invalidate the assumption.
制御されたコイル製造に有用な延性
Nickel 201 offers useful ductility for controlled coil fabrication. In hot caustic equipment fabrication, this supports the design by addressing part of the combined exposure: caustic concentration, maximum metal temperature, oxidizing salts, sulfur contamination, plate thickness, forming strain, cleaning, and shutdown deposits. A quotation should not claim this benefit without confirming grade identity and ordered condition. The project should identify the exact location where this property is needed and the condition that would invalidate the assumption.
証明書やPMI計画によって容易に検証できる、単純な化学反応
Nickel 201 offers simple chemistry that is easy to verify by certificate and PMI planning. In hot caustic equipment fabrication, this supports the design by addressing part of the combined exposure: caustic concentration, maximum metal temperature, oxidizing salts, sulfur contamination, plate thickness, forming strain, cleaning, and shutdown deposits. Its practical value appears at the most severe local zone, not in a generic property table. The project should identify the exact location where this property is needed and the condition that would invalidate the assumption.
The selection boundary is equally important: Nickel 201 is not a universal answer for every alkaline process. Oxidizing salts, sulfur compounds, concentration, temperature, and contamination by other process chemicals must be considered. Low carbon does not make the alloy immune to every caustic process. Temperature, concentration, contaminants, stress, deposits, and cleaning chemistry still define suitability. This is why responsible technical writing distinguishes a defensible candidate from a universal recommendation.
Room-temperature tensile values and handbook corrosion summaries are useful for screening Nickel 201, but acceptance should use ASTM B162, project design values, and the heat-specific certificate. For hot caustic equipment fabrication, corrosion behavior must be evaluated at representative concentration, temperature, contaminants, aeration, velocity, deposits, and stress.
プロセスサイクル全体に基づいて、物的証拠の立証を行う
Material selection for Nickel 201 plate for hot caustic equipment ASTM B162 supplier should use a timeline rather than one normal operating point. Startup, stable operation, process upset, cleaning, and shutdown can each create a different corrosion potential, temperature, mechanical load, or wetting condition. A process record that captures only nominal chemistry can miss the short stage that determines service life.
| 工程段階 | 重大な懸念事項 | 設計レビューに関する質問 |
|---|---|---|
| スタートアップにおける株式希薄化 | Concentration and local temperature can change rapidly. | Record concentration, temperature, and circulation sequence. |
| Hot operation | Caustic concentration and temperature control the base corrosion case. | Use the maximum local exposure and heat-transfer condition. |
| 汚染 | Oxidizing salts and sulfur compounds can change performance. | Define impurity limits and process carryover. |
| 掃除 | Residual caustic can concentrate at low points. | Specify drainage, rinse quality, and verification. |
| 遊休期間 | Deposits and air ingress alter local chemistry. | Plan dry preservation and accessible inspection points. |
The table is also a practical RFQ tool. The supplier does not need confidential process know-how, but the material review does need enough information to distinguish normal exposure from the worst credible combination. For hot caustic equipment fabrication, that means documenting the range behind each phrase in the service summary: caustic concentration, maximum metal temperature, oxidizing salts, sulfur contamination, plate thickness, forming strain, cleaning, and shutdown deposits.
For hot caustic equipment fabrication, separate bulk fluid temperature from actual Nickel 201 metal temperature. Heat transfer, insulation, deposits, poor flow, direct heat, and ambient cooling can move the metal above or below the fluid value. Also separate average chemistry from local chemistry around the ordered plate; low-flow zones, vapor boundaries, deposits, and drying surfaces can concentrate dilute species.
The most credible Nickel 201 recommendation includes a stopping rule. Nickel 201 is not a universal answer for every alkaline process. Oxidizing salts, sulfur compounds, concentration, temperature, and contamination by other process chemicals must be considered. Low carbon does not make the alloy immune to every caustic process. Temperature, concentration, contaminants, stress, deposits, and cleaning chemistry still define suitability. When the available data for hot caustic equipment fabrication do not close those questions, the design authority should use plant history, a corrosion specialist, or representative testing before final approval.
このサービスが、本来は優れた合金であってもその性能を損なわせてしまう仕組み
A useful material article should say how a purchase can fail. In hot caustic equipment fabrication, damage is rarely distributed perfectly evenly. It starts where chemistry concentrates, stress rises, flow changes, surfaces remain wet, temperature peaks, or inspection access is weakest. The following mechanisms turn the alloy discussion into locations and controls that can be put on drawings and inspection plans.
| 故障メカニズム | 典型的なフィールド信号 | エンジニアリングまたは調達管理 |
|---|---|---|
| Concentration-driven attack | Accelerated loss at hot or concentrated locations | Map temperature, evaporation, and circulation |
| Grade-temperature mismatch | The selected carbon basis is unsuitable for thermal exposure | Verify grade choice against service and manufacturing temperatures |
| Contaminant-assisted corrosion | Unexpected attack after oxidizing or sulfur carryover | Set impurity limits and investigate process excursions |
| 表面汚染 | Embedded foreign material creates local staining or attack | Use clean tooling and verified final cleaning |
The mechanisms identified for hot caustic equipment fabrication can interact. Local corrosion may reduce section and raise stress; vibration may damage a surface; deposits may change temperature and chemistry; fabrication contamination may create the first active site. The Nickel 201 plate decision therefore belongs with geometry, process control, cleaning, and maintenance.
Inspection should be risk-based, not evenly distributed for convenience. The article-specific emphasis is: Make carbon result, N02201 identity, dimensions, surface, MTC, PMI capability, and traceability explicit receiving hold points. That focus belongs in baseline records before service, so later readings can be compared with the same physical locations and methods.
一般的な代替案との選択上のトレードオフ
A credible specification for hot caustic equipment fabrication explains why Nickel 201 plate is preferred over alternatives in the same supplied form. The purpose is not to rank alloys from cheap to expensive; it is to identify the environmental or mechanical condition that changes the decision.
| 同じ形式の代替案 | 実現可能な場合 | ニッケル201が依然として選ばれる理由 |
|---|---|---|
| ニッケル200メッキ板 | 多くの苛性環境向けの商業用純ニッケル | 温度によっては、低炭素のニッケル201系材の使用が必要となる場合がある |
| モネル400プレート | 海水およびニッケル・銅に対する性能が実証済み | 異なる酸および酸化剤の範囲に対応しています |
| インコロイ800H プレート | 高温荷重に対する制御条件 | これは、耐食性を重視したモリブデン合金の代替品ではありません。 |
| 316Lステンレス鋼板 | 初期コストが低く、入手しやすい | 局所的な腐食や高温に対する余裕度が低くなる可能性がある |
When comparing Nickel 201 plate with these alternatives, use the same process envelope, design life, corrosion allowance, fabrication route, inspection plan, and delivery assumption. One quote may look lower because it assumes a different condition, looser tolerance, fewer tests, shorter usable dimensions, or a narrower service window.
The strongest decision statement for hot caustic equipment fabrication is conditional: select Nickel 201 when the documented service and design require its combination of properties; use a lower-alloy option when verified plant history or representative data show adequate margin; use a more specialized alloy when the process falls outside the boundary described above.
最終検査をクリアできる証拠資料一式を作成する
Quality control for Nickel 201 plate for hot caustic equipment ASTM B162 supplier should answer four separate questions: Is the material the ordered alloy? Is it the ordered plate and condition? Does it meet the specified dimensions and tests? Can every delivered item be traced to the evidence package? A pass in one category does not compensate for a gap in another.
| 証拠品 | 確認すべき事項 | その内容 |
|---|---|---|
| 製粉証明書 | 熱番号、グレード、UNS、規格、化学成分、機械的特性、状態および寸法 | 文書化された製品の適合性を確認する |
| PMI | 合意された頻度および場所での成績確認 | 材料の混入リスクを低減しますが、証明書に代わるものではありません |
| 寸法レポート | 厚さマッピング、幅および長さの検査、平坦度の確認、表面検査、熱伝達、および指定された超音波検査 | 製造前に使用可能な形状であることを確認する |
| 表面検査 | 順序付き受入基準と欠陥の処理 | 化学分析の結果では明らかにならない損傷を発見する |
| 非破壊検査 | 指定されている場合は、方法、適用範囲、校正および受入基準 | 内部または表面の不連続性によるリスクに対処する |
| トレーサビリティマップ | 熱源やアイテムのマークから、切断位置または設置位置へのリンク | 処理後も証拠を保全する |
| 梱包記録 | 状態、保護措置、梱包の痕跡、および写真 | 輸送および受入管理に対応しています |
The mill certificate is the central material record, but it is not a corrosion test for hot caustic equipment fabrication. It shows that a heat met the ordered product requirements. Service suitability comes from the material selection basis, design calculation, fabrication quality, and operating envelope.
PMI is a useful identity control for Nickel 201, especially after processing or in mixed-material shops. It does not prove every controlled element, heat-treatment condition, mechanical property, or corrosion response. The procedure for this plate should define instrument capability, calibration, surface preparation, frequency, and positive identification of each reading.
For dimensional and surface inspection, the article-specific priority is: Make carbon result, N02201 identity, dimensions, surface, MTC, PMI capability, and traceability explicit receiving hold points. In addition, the general plate inspection scope is thickness mapping, width and length checks, flatness review, surface examination, heat-number transfer, and any specified ultrasonic examination. Acceptance criteria should be written before inspection begins, including who may approve a repair or concession.
Third-party inspection of the Nickel 201 plate is most effective when hold points are defined in the purchase order. For hot caustic equipment fabrication, likely points include certificate review, identity, dimensions, test witnessing where required, surface, marking, packing, and final document release. A late request can delay shipment without improving completed work.
Before releasing Nickel 201 plate for hot caustic equipment fabrication, reconcile the offer, purchase order, certificate, physical marks, and inspection report. Resolve grade suffixes, ASTM B162 edition, dimensions, heat treatment, test exceptions, and quantity while the material is still identifiable and replaceable.
Article-specific credibility check: Credibility depends on stating the process temperature boundary and contaminant assumptions instead of presenting Nickel 201 as universally caustic-proof. This evidence should be available before shipment or identified as a formal hold point; a catalogue statement or generic certificate example is not heat-specific proof for the delivered plate.
購入者が名目上の規模以外に明示しなければならない事項
The product description should convert the engineering drawing into measurable supply terms. For Nickel 201 plate, that means thickness, width, length, flatness, edge condition, rolling allowance, and final cut plan. Define thickness, width, length, flatness, forming allowance, design minimum, corrosion allowance, and maximum fabrication and service temperatures.
| 次元 | 記載すべき事項 | なぜそれが重要なのか |
|---|---|---|
| 厚さ | 公称値、許容差、最小設計基準 | 厚さは、圧力、荷重、成形、および腐食余裕に影響を与えます |
| 幅と長さ | 正確な寸法または最小使用可能寸法 | ネスティング、溶接配置、圧延、および輸送の管理 |
| 平坦度 | 標準公差、またはそれより厳しいプロジェクト値 | 組み付け、成形、および製造の所要時間に影響を与える |
| エッジ | ミル加工または切断状態および仕上げ代 | 溶接準備と有効面積を管理する |
| オリエンテーション | 巻き方向や設置場所に関する要件 | 成形およびプロジェクトのトレーサビリティに関わる可能性あり |
Tolerance for Nickel 201 plate should be tied to function. Tightening every dimension can add cost and lead time without improving reliability, while leaving a critical dimension open transfers risk to fabrication. Ask which dimensions govern fit, forming, machining, joining, or line setup for hot caustic equipment fabrication before sending the inquiry.
A dimensional inspection report is especially useful when material crosses borders before fabrication. It allows the buyer to resolve a discrepancy before the Nickel 201 plate reaches a busy shop or remote site, where replacement time and handling are much more expensive.
材料の性能を守る製造管理
Nickel 201 should be processed as a corrosion-critical nickel alloy, not as ordinary shop stock. The relevant route includes cutting, edge preparation, forming, rolling, welding, dimensional restoration, and final cleaning. Protect the soft nickel surface from embedded iron, rough handling, sulfur-bearing compounds, and uncontrolled thermal exposure.
清潔さと分別
Use clean work surfaces and tools that will not embed free iron or carry sulfur, lead, zinc, incompatible copper contamination, chlorides, or unknown residues onto the Nickel 201 plate for hot caustic equipment fabrication. Marking compounds, lubricants, cleaners, media, and temporary attachments should be approved for this alloy and service.
フォーム固有の処理
Fabrication of Nickel 201 plate for hot caustic equipment fabrication should sequence cutting, forming, edge preparation, fit-up, and joining around the final geometry. Forming strain, bend radius, rolling direction where relevant, and trim allowance should be settled before nesting.
Large Nickel 201 plate areas in hot caustic equipment fabrication need distortion control. Balanced joining sequence, temporary restraint designed for removal, realistic gaps, and repeatable dimensional references are more reliable than forcing misaligned plate into place.
接合と熱入力
Joining procedures for Nickel 201 in hot caustic equipment fabrication should be qualified by the fabricator for section, joint design, position, consumable, shielding, heat input, interpass control, and required examination. Clean each pass as required and prevent arc strikes or temporary attachments outside the approved procedure.
Do not assume a visually acceptable joint has preserved corrosion or high-temperature performance. For hot caustic equipment fabrication, joint geometry, residual stress, surface condition, dilution, heat tint, crevices, and access for final cleaning can matter as much as strength. The project specification should define post-join cleaning and acceptance.
最終的な表面仕上げおよび寸法に関するリリース
Remove contamination and unacceptable discoloration from the Nickel 201 plate by an approved method that does not leave embedded abrasive or uncontrolled roughness. Verify the dimensions critical to hot caustic equipment fabrication after final thermal and mechanical operations, because early measurements do not capture later distortion.
技術的に類似した2つの見積もりが、なぜ異なるリスクを伴うのか
The price of Nickel 201 plate reflects alloy content, melting and processing route, size, condition, tolerance, order quantity, test scope, current availability, yield, packing, freight, and payment terms. A buyer should normalize those variables before treating one quotation as cheaper.
Article-specific commercial emphasis: A credible supplier quote identifies the low-carbon grade, ordered condition, plate size, test evidence, clean packing, and any minimum production quantity. The comparison should also include the cost of clarification, inspection, fabrication yield, schedule exposure, and replacement if a deviation is found after delivery.
Quotation evidence for this inquiry: The offer should not substitute Nickel 200 or use the generic word nickel without written engineering approval and a revised thermal review. Where a price is requested, use the same currency, quantity, dimensions, condition, processing, test scope, packing, delivery term, destination, and validity date for every supplier.
| コスト要因 | 変更点 | 商業的効果 |
|---|---|---|
| 合金および状態 | 化学成分、熱処理および機械的要件 | 中核となる生産ルートを定義する |
| 寸法 | サイズ、公差、および使用可能長さまたは面積の要件 | ミル歩留まりおよび加工歩留まりの変化 |
| 数量 | 総重量、品目数、およびリピート注文の可能性 | キャンペーンの収益性および最低注文数量に影響します |
| 検査 | 試験、立会い、書類および特別検収 | 直接コストとスケジュールのホールドポイントを追加します |
| 処理 | 切断、またはその他合意された下処理 | 購入側の設定作業を軽減できるが、供給側の作業が増える |
| 物流 | 梱包サイズ、保護措置、配送ルート、および配達条件 | 変更の取り扱い、運賃および損害リスク |
Lead time for Nickel 201 plate should be split into material availability, production, testing, inspection release, document approval, packing, and transport to the destination. Ask which dates are committed and which are estimates; a short production promise with an undefined release stage may not protect the hot caustic equipment fabrication schedule.
梱包と輸送
The packing concept for Nickel 201 plate intended for hot caustic equipment fabrication is dry separators between plate faces, edge and corner protection, rigid pallet support, weather barrier, and marks visible without unpacking. Packages should keep heats and sizes identifiable, prevent contaminating contact, and allow safe unloading with the equipment available at destination.
For export of this Nickel 201 plate, agree package dimensions, gross and net weight, lifting points, moisture barrier, destination handling, and mark format before dispatch. Photograph material and closed packages. Receiving records should separate transport damage from the manufacturing condition needed for hot caustic equipment fabrication.
Lifecycle cost is the more useful final measure for hot caustic equipment fabrication. It includes purchase, fabrication, inspection, installation, downtime, maintenance access, monitoring, replacement interval, and consequence of failure. Choosing Nickel 201 is justified only when it improves that equation under the documented service conditions.
購入担当者およびエンジニアによるレビューの流れ
The following sequence keeps the Nickel 201 plate decision connected to the equipment rather than allowing technical and commercial reviews to drift apart. Each gate should produce a short record before the next commitment is made.
- Freeze the service envelope: record normal, maximum, upset, cleaning, and shutdown conditions for hot caustic equipment fabrication, including chemistry, temperature, pressure, load, velocity, deposits, and duration.
- 材料選定の根拠を承認する：ニッケル201およびUNS N02201が選定された理由、検討された代替案、およびどのような状況で再選定が行われるかを確認する。.

- 出荷・受入：製造前に書類と実物のマークを照合し、出荷状態を検査し、不一致品を隔離し、最終的な機器に至るまでのトレーサビリティを確保する。.
For repeat orders, update the specification with actual fabrication yield, inspection findings, service history, and logistics performance. The second Nickel 201 plate purchase should be more precise than the first, not merely a copy of an old purchase order.
サプライヤーへの送付前の最終的な見積依頼書の確認

Add the article-specific notes directly: dimensional focus – Define thickness, width, length, flatness, forming allowance, design minimum, corrosion allowance, and maximum fabrication and service temperatures. Fabrication focus – Protect the soft nickel surface from embedded iron, rough handling, sulfur-bearing compounds, and uncontrolled thermal exposure. Inspection focus – Make carbon result, N02201 identity, dimensions, surface, MTC, PMI capability, and traceability explicit receiving hold points.
Ask suppliers to quote the requested Nickel 201 basis first and place alternatives on separate lines. Clarify whether plate weights are theoretical or actual, whether dimensions are exact or approximate, and whether delivery means mill completion or arrival at the project destination.
よくある質問
Is Nickel 201 automatically suitable for hot caustic equipment fabrication?
No. It is a defensible candidate because nickel 201 plate combines commercially pure nickel caustic resistance with a low-carbon basis suited to hotter service than nickel 200 can normally support. Final approval still requires the complete service envelope, design basis, fabrication plan, and project authority review. Low carbon does not make the alloy immune to every caustic process. Temperature, concentration, contaminants, stress, deposits, and cleaning chemistry still define suitability.
このプレートには、どのASTM規格が適用されますか？
This procurement guide uses ASTM B162 for Nickel 201 plate. Confirm the current edition, any ASME or owner requirement, and the exact product condition on the purchase order.
製粉証明書には何を記載すべきですか？
For Nickel 201 plate intended for hot caustic equipment fabrication, check heat number, UNS N02201, ASTM B162, chemistry, mechanical results required by the order, condition, dimensions, quantity, and traceable identification. Project-specific test results should be indexed clearly.
PMIは製粉証明書に代わるものですか？
No. For Nickel 201 plate used in hot caustic equipment fabrication, PMI is an identity check within the capability of the method and instrument. It does not replace heat-specific chemistry, heat-treatment records, mechanical tests, dimensions, or full traceability. Use PMI and the certificate together.
プレートにとって、どの寸法が不可欠ですか？
For Nickel 201 used in hot caustic equipment fabrication, state thickness, width, length, flatness, edge condition, rolling allowance, and final cut plan. Define which tolerances follow ASTM B162, which are tighter, how they will be measured, and how much fabrication allowance is included.
どの製造上の問題に最も注意を払うべきでしょうか？
For this application: Protect the soft nickel surface from embedded iron, rough handling, sulfur-bearing compounds, and uncontrolled thermal exposure. More generally, protect the nickel-alloy surface, control strain and heat input, use qualified procedures, and verify final geometry after all thermal and mechanical operations.
ベースライン検査はどの部分に重点を置くべきか？
Use the service damage map rather than equal spacing. Make carbon result, N02201 identity, dimensions, surface, MTC, PMI capability, and traceability explicit receiving hold points. Keep permanent location references so future readings are comparable.
なぜ同じグレードの商品でも、見積もりがこれほど大きく異なるのでしょうか？
Quotes may assume different size, tolerance, condition, quantity, testing, usable yield, production route, packing, and delivery. A credible supplier quote identifies the low-carbon grade, ordered condition, plate size, test evidence, clean packing, and any minimum production quantity. Normalize those assumptions before comparing unit price.
What information should accompany a request for Nickel 201 plate for hot caustic equipment ASTM B162 supplier?
For Nickel 201 plate for hot caustic equipment ASTM B162 supplier, send Nickel 201, UNS N02201, ASTM B162, complete plate dimensions, quantity, condition, service data, fabrication route, inspection and document requirements, destination, delivery term, and required arrival date. Include drawings when allowances are difficult to describe in text.
Final Procurement Position on Nickel 201 Plate
