Hastelloy C22 is a omnipotent of nickel, chromium and molybdenum mixed alloy, with better corrosion resistance performance.

Characteristic as below Hastelloy C22 is a omnipotent of nickel, chromium and molybdenum mixed alloy, with better corrosion resistance performance than other alloys, for example, Hastelloy C276 alloy, C4 alloy and 625 alloy. 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 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. 

Metallurgical structureHastelloy C22 is face-centered cubic lattice structure.

Corrosion resistanceHastelloy C22 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten makethis corrosion resistancebetter.Hastelloy C22 is one of a few material that can resist thecorrosion of moist chlorine, hypochlorite and chlorine dioxide, this alloyhave prominent corrosion resistanceto high concentration chlorate( iron chloride and copper chloride).

 Application fieldHastelloy C22 is widely used in the chemical field and petrifaction field, such as the element of chloride organic and catalyze system.This material especially suit for high temperature environments, impure inorganic acid and organic acid (such as formic acid and acetic acid), sea-water corrosion environments. Other application field1.Acetic acid/acetyl oxide2.Acid dipping 3.Cellophane paper manufacture4.Chloride system5.
