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