Alloy 600

Alloy 600, commonly known as INCONEL® 600, is a nickel-chromium alloy with good oxidation resistance at high temperatures and resistance to chloride-ion stress-corrosion cracking. The high nickel content enables it to retain considerable resistance to neutral and alkaline salt solutions and the use in caustic environments. Its chromium content gives the alloy resistance to sulfur compounds and various oxidizing environments. Applications include steam generators, chemical processing, furnaces, and jet engines.
