Инколой 825
A nickel-iron-chromium alloy with added molybdenum and copper. Specifically engineered to provide exceptional resistance to corrosive environments, including sulfuric and phosphoric acids, as well as sea water.
View Incoloy 825 DetailsWhat are Incoloy Alloys?
Incoloy alloys are superalloys primarily based on Nickel, Iron, and Chromium. They were developed as a more economical alternative to the Nickel-based Inconel series while still maintaining excellent high-temperature and corrosion-resistant properties.
The addition of Iron makes Incoloy more cost-effective, while the high Chromium content ensures superior resistance to oxidation and carburization.
Key Differences
Nickel Content: Inconel contains >50% Nickel, whereas Incoloy typically contains less than 50% Nickel.
Application Focus: While Inconel is used for extreme heat (jet engines), Incoloy is the preferred choice for industrial heating, petrochemical piping, and aqueous corrosion environments where cost-efficiency is a factor.
| Сплав | Key Chemical Elements | Primary Characteristics | Best For |
|---|---|---|---|
| Инколой 800 | Ni (30-35%), Cr (19-23%), Fe (Bal) | Excellent resistance to oxidation and carburization at high temperatures. | Heat Treatment, Petrochemical |
| Инколой 825 | Ni (38-46%), Cr, Mo, Cu, Ti | Superior resistance to reducing and oxidizing acids (Sulfuric/Phosphoric). | Chemical Processing, Oil & Gas |
What forms of Incoloy do you supply?
We supply Incoloy in seamless pipe, welded tube, plate, sheet, round bar, wire, and fittings (flanges, elbows, tees). We can also provide custom forgings.
What is the difference between Incoloy 800, 800H, and 800HT?
The difference lies in the Carbon, Aluminum, and Titanium content. Incoloy 800 is the general grade. 800H has controlled carbon (0.05-0.10%) for better creep strength. 800HT adds Al+Ti restrictions for maximum high-temperature strength.
