ASTM B366 Hastelloy C22 Alloy Steel Elbows Codos
ASTM B366 Hastelloy C22 Alloy Steel Elbows Codos
YUHONG supplies ASTM B366 Hastelloy C22, it is a omnipotent of nickel, chromium and molybdenum mixed alloy, with better corrosion resistance performance than other alloys. Hastelloy C22 have a good resistance performance to pitting, crevice corrosion and stress corrosion cracking, have excellent inoxidability water medium performance, including the wet-chlorine, nitric acid or oxidizing acid mixed acid with chloride ion.
Meantime, Hastelloy C22 possesses perfect resistance to reduction and oxidation of processing enviroments, then it can be used in some complicated environment or with many different manufacture target factory depend on the omnipotent performance.
Hastelloy C22 also possess prominent resistance performance to different chemical environments, including strong oxidizing matter, such as iron chloride, copper chloride, chlorine, heat pollution liquid(organic and inorganic), formic acid, acetic acid, acetyl oxide, sea water and salting liquid and so on.
Hastelloy C22 alloy can resist the grain boundary precipitate form when jointing heat affected zone, this performance made it can applied in many kinds of chemical processing.
