Hastelloy C22 Pipe & Tubing

Hastelloy C22, generally known as alloy C22, is an extremely versatile austenitic nickel-chromium-molybdenum-tungsten alloy with advanced protection to pitting, crevice rust and stress corrosion cracking. The higher chromium content offers high-quality resistance to oxidizing media when the molybdenum or tungsten content gives good quality resistance to decreasing media. This nickel metal alloy also offers outstanding protection to oxidizing aqueous media such as wet chlorine and also combinations including nitric acid or even oxidizing chemicals with chlorine ions. Additional corrosives Hastelloy C-22 have resistance to are oxidizing acidity chlorides , wet chlorine , formic and also acetic chemicals , ferric and also cupric chlorides , sea water , brine along with several mixed or polluted chemical solutions , both organic or inorganic . This nickel alloy also provides ideal protection to environments when reducing and also oxidizing situations are encountered in procedure streams. This can be helpful in multi- purpose plants where such “upset” situations occur regularly.
This nickel alloy prevents the formation of grain-boundary precipitates in the weld heat-affected area, hence making it very ideal for nearly all chemical procedure applications in the as-welded condition.
Alloy C-22 ought not to be utilized in service temperature above 1250° F because of the formation of unfavorable phases which form above this high temperature.
