Hastelloy C 22 (N06022) alloy is a nickel based high-temperature alloy composed of elements such as nickel, molybdenum, cobalt, and tungsten, with a nickel content of approximately 60%. It is a versatile nickel molybdenum cobalt tungsten alloy that has 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, crevice corrosion and stress corrosion cracking. It has excellent antioxidant water medium capabilities, including mixed acids of wet chlorine, nitric acid, or oxidizing acids containing chloride ions.

Meanwhile, Hastelloy C 22 (N06022) Hastelloy alloy also has ideal resistance to reducing and oxidizing environments. With this versatile performance, it can be used in some challenging environments or in various production purpose factories. This alloy has exceptional resistance to various chemical environments, including strong oxidizing substances, such as ferric chloride, copper chloride, chlorine, thermal pollution solutions (organic and inorganic), formic acid, acetic acid, acetic acid, seawater and salt solutions. This alloy has the ability to resist the formation of grain boundary precipitation in the welding Heat-affected zone, so that it can also adapt to the application of many chemical processes in the welding state.
