Hastelloy® Alloy 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. The high chromium content in Hastelloy® Alloy C22 provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media.
