Hastelloy C22(n06022) Hastelloy Overview
Hastelloy C22(n06022) is a nickel-based high-temperature alloy composed of nickel, molybdenum, cobalt, tungsten and other elements. The nickel content is about 60%. It is a general-purpose Ni-Cr-Mo-W alloy whose overall corrosion resistance is superior to other existing Ni-Cr-Mo alloys, including Hastelloy C- 276, C4 alloy and 625 alloy. Hastelloy C22 has good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. It has excellent antioxidant capacity in aqueous media, including wet chlorine, nitric acid or mixed acids containing chloride ions.
At the same time, the hastelloyc22(n06022)Hastelloy alloy is also ideally resistant to the reducing and oxidizing environments encountered during the process. With this versatile performance, it can be used in some troublesome environments, or in factories for various production purposes. Hastelloy C22(n06022) has abnormal resistance to various chemical environments, including strong oxidizing substances such as ferric chloride, copper chloride, chlorine and thermally contaminated solutions. Liquids (organic and inorganic), formic acid, acetic acid, acetic anhydride, seawater and salt solutions, etc. Hastelloy C22(n06022) alloy has the ability to resist the heat affected zone (HAZ) grain boundary precipitation, and is suitable for a variety of chemical processes in the welded state.
