Hastelloy C-22 Wrought nickel-base superalloy

Hastelloy C-22 Wrought nickel-base superalloy

Hastelloy C-22 alloy steel is a omnipotent, nickel-chromium-molybdenum-tungsten alloy than other existing nickel chromium molybdenum alloy has better overall corrosion resistance, including Hastelloy C276, C4 alloy and 625 alloy. Hastelloy C22 alloy has good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking ability. It has excellent antioxidant ability to water medium, including wet chlorine, nitric acid or oxidizing acid containing chloride ions mixed acid. At the same time, Hastelloy C22 alloy also has the ideal resistance encountered in the process of reducing and oxidizing environment. Rely on the universal performance, it can be used in some headache environment, or used in a variety of factory production purpose. Hastelloy C22 alloy has abnormal resistance of variouschemical environment, including strong oxidizing substances, such as ferric chloride, copper chloride, chlorine, thermal pollution solution (organic, inorganic), formic acid, acetic acid, acetic anhydride, water and salt solution, etc. Hastelloy C22 alloy in welding heat affected zone is to resist the ability of grain boundary precipitation formation, so make it under welding condition also can adapt many kinds of the application of chemical process.
