Hastelloy C-22
Overview of Hastelloy C-22（N06022）
Hastelloy C22 (N06022) is a nickel-based superalloy composed of elements such as nickel, molybdenum, cobalt and tungsten, with a nickel content of approximately 60%.
It is a universal nickel-chromium-molybdenum-tungsten alloy, which has better overall corrosion resistance than other existing nickel-chromium-molybdenum alloys, including Hastelloy C-276, C4 alloy and 625 alloy.
Hastelloy C22 alloy has excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking.
It has excellent resistance to oxidizing water media, including wet chlorine, nitric acid or mixed acids of oxidizing acids containing chloride ions.
