HASTELLOY Alloy C-22 is a nickel-chromium-molybdenum alloy with enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking. It resists the formation of grain boundary precipitates in the weld-heat affected zone, making it suitable for use in the as-welded condition.
C-22 demonstrates outstanding resistance to both reducing and oxidizing media and can be used where "upset" conditions are likely to occur. It possesses excellent weldability and high corrosion resistance as consumable filler wires and electrodes. The alloy has proven effective as a filler wire in applications where other corrosion-resistant wires have failed.
C-22 can be easily cold-worked due to its ductility, with cold-forming being the preferred method of forming. More energy is required as the alloy is generally stiffer than austenitic stainless steels.
