Hastelloy C22 Supplier

Hastelloy C22, also known as alloy C22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. Alloy C-22 should not be used in service temperatures above 1250° F due to the formation of detrimental phases which form above this temperature. Hastelloy C-22 has resisted the formation of grain boundary precipitates in the weld heat-affected zone, making it a candidate for most chemical and petrochemical processing applications in the as-welded condition. The alloy has resisted both general and localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.
