Hastelloy C22 N06022 Tube

Hastelloy C22 N06022

The alloy is a nickel-based superalloy composed of elements such as nickel, molybdenum, cobalt, and tungsten, with a nickel content of about 60%. It is an all-around nickel-molybdenum-cobalt-tungsten alloy with better overall corrosion resistance than other existing nickel-molybdenum-cobalt-tungsten alloys, including Hastelloy C-276, 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 oxidizing aqueous media, including wet chlorine, nitric acid or mixtures of oxidizing acids containing chloride ions.

Hastelloy C22 alloy is suitable for a variety of chemical process industries containing oxidizing and reducing media. The higher content of molybdenum and chromium makes the alloy resistant to the corrosion of chloride ions, and the tungsten element further improves its corrosion resistance. Hastelloy C22 is one of the few materials that can resist the corrosion of moist chlorine, hypochlorite and chlorine dioxide solutions. The alloy has excellent corrosion resistance to high concentration chloride salt solutions (such as ferric chloride and copper chloride).
