Incoloy 803 is an iron-nickel-chromium alloy specifically engineered for petrochemical, chemical, and thermal processing applications. Featuring higher nickel and chromium content than Incoloy 800H and 800HT, this material achieves optimal performance through a balanced nickel-iron-chromium ratio across temperature ranges from 1550°F (840℃) to 2100F (1150℃). As an economical material, Incoloy 803 delivers exceptional high-temperature corrosion resistance in oxidative, sulfidizing, and carburizing environments. It demonstrates outstanding stress fracture strength at elevated temperatures. These properties, combined with exceptional resistance to carburization and cyclic oxidation, make Incoloy 803 an ideal choice for demanding industrial applications.
The density of the alloy is ρ=7.86g/cm³.
