Hastelloy C22 Features:

Hastelloy® C22 (UNS N06022/2.4602) Alloy C22 is a nickel-chromium-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 56% nickel, 22% chromium, and 13% molybdenum, with additions of iron, tungsten, and cobalt. Hastelloy C22 is a versatile nickel-chromium-molybdenum-tungsten alloy with better overall corrosion resistance than other existing nickel-chromium-molybdenum alloys, including Hastelloy C276, C4 alloy, and 625 alloy.


Hastelloy C22 alloy has good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. It has excellent resistance to oxidative aqueous media including wet chlorine, nitric acid or a mixture of oxidative acids containing chloride ions. At the same time, Hastelloy C22 alloy also has ideal resistance to reducing and oxidizing environments encountered in the process. Relying on this versatile performance, it can be used in some troublesome environments, or in a variety of production purpose factories. 


Hastelloy C22 alloy is exceptionally resistant to a variety of chemical environments, including strong oxidizing substances such as ferric chloride, cupric chloride, chlorine, hot contaminated solutions (organic and inorganic), formic acid, acetic acid, acetic anhydride, seawater and salt solution, etc. Hastelloy C22 alloy has the ability to resist the formation of grain boundary precipitation in the welding heat affected zone, which makes it suitable for many chemical process applications in the welded state.
