Hastelloy C22 is a nickel-chromium-molybdenum-tungsten wrought alloy with superior resistance to both oxidizing and reducing corrosive media. It offers outstanding protection against pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-containing environments. With ultra-low carbon content, it resists carbide precipitation during welding and maintains excellent intergranular corrosion resistance. Widely used in chemical processing, flue gas desulfurization, pharmaceu

Advantage

1.Excellent resistance to both oxidizing and reducing corrosive media 2.Outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion cracking 3.Superior weldability with minimal intergranular corrosion risk in heat-affected zones 4.Good high-temperature stability and mechanical properties for severe service conditions
