ASTM B366 N06022 Hastelloy C22 180 Degree Elbow Alloy Steel Fittings B16.9
Hastelloy C22 is an all-powerful nickel-chrome-molybdenum-tungsten alloy that has better overall fu corrosion resistance than other existing nickel-chrome-molybdenum alloys, including C-276, C4, and 625. Hastelloyc 22 alloy has good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. It has a unique ability to resist yang chemical water media, including wet lv, xiao acid or a mixture of yang chemical acids containing lv compound ions. At the same time, HastelloyC22 alloy also has ideal resistance to the reducing and yang chemical environment encountered during the process. Depending on the performance of this WAN energy, it can be used in some troublesome environments, or in multiple production purpose plants.
Hastelloy C22 alloy has exceptional resistance to various chemical environments, including strong oxidizing substances, such as lv iron, lv copper, chlorine, hot polluted solution (you machine without ji), jia acid, yi acid, vinegar suan anhydride, seawater and salt solutions. HastelloyC22 alloy has the ability to resist grain boundary precipitation formation in the welding heat affected zone, which makes it suitable for many chemical processes in the welding state.
