C22
Type Hastelloy C-22 alloy is one of the widely used nickel-chromium-molybdenum corrosion-resistant alloy grades. With its advanced chemical composition, it provides outstanding resistance to both oxidizing and reducing environments, and excellent protection against pitting, crevice corrosion, and stress corrosion cracking. Grade Hastelloy C-22 is commonly applied in chemical, pharmaceutical, and environmental industries, particularly in processes involving mixed acid and chloride-containing solutions.
