Incoloy is a nickel-chromium-iron alloy designed to resist oxidation and carbonization at elevated temperatures. There are many types of ncoloy alloys: common ones such as Incoloy 800, Incoloy 800H, Incoloy800HT, Incoloy825, Incoloy840, Incoloy901, Incoloy925, Incoloy20, Incoloy330, Incoloy25-6 Mo, and the like. The metal nickel-iron-chromium-based nickel-based corrosion-resistant alloy contains a small amount of metal elements such as molybdenum and copper. Among the reducing acids and oxidizing acids, it has good corrosion resistance and good resistance to stress corrosion cracking, pitting corrosion and crevice corrosion. It has excellent corrosion resistance to sulfuric acid and phosphoric acid. This alloy has good hot and cold processing properties and is easy to cold form and weld. The main products of this alloy are bar, pipe, sheet, strip, wire and forging, etc., mainly used in chemical, petrochemical, nuclear industry and rare metal refining industries.
