UNS N06022 Wrought nickel-base super alloy

UNS N06022 alloy 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. UNS N06022 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, UNS N06022 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. UNS N06022 alloy has abnormal resistance of various chemical 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. UNS N06022 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.
