Incoloy 803

Designated as UNS S35045, Incoloy 803 (also known as Alloy 803) is an iron-nickel-chromium alloy with higher nickel and chromium contents. It has exceptional resistance to high-temperature corrosion in oxidation, sulfidation and carburization environments. Alloy 803 also exhibits excellent stress-rupture strengths at elevated temperatures. Incoloy 803 is used primarily for petrochemical, chemical and thermal processing applications, as well as ethylene furnaces piping.
