Inconel 617
Combines metallurgical stability, strength, and oxidation resistance at high temperatures. Widely used in gas turbines and petrochemical plants for combustion cans and ducts.
View Inconel 617 Details
Inconel 625
High strength and outstanding corrosion resistance without heat treatment. The addition of molybdenum and niobium acts to stiffen the alloy matrix, providing high fatigue strength.

Inconel alloys are classified as Superalloys. They are specifically engineered to maintain structural integrity in environments where lesser metals would melt, oxidize, or succumb to creep deformation.
When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. This makes them indispensable in jet engines, chemical processing reactors, and marine environments.
| Alloy | UNS No. | Key Characteristic | Typical Application |
|---|---|---|---|
| Inconel 600 | N06600 | Standard heat & corrosion resistance. Immune to chloride stress cracking. | Heat treating muffles, chemical processing. |
| Inconel 601 | N06601 | Maximum oxidation resistance up to 2200°F (1200°C). | Radiant tubes, thermal reactors, igniters. |
| Inconel 625 | N06625 | Excellent aqueous corrosion resistance + high strength. | Marine exhaust, seawater piping, pollution control. |
| Inconel 718 | N07718 | Highest strength (Age-Hardenable). Excellent weldability. | Jet engine disks, liquid fuel rockets, bolts. |
