INCOLOY alloy 803

Designed for use in petrochemical, chemical and thermal processing applications, the alloy provides an exceptional level of high-temperature corrosion resistance in oxidation, sulfidation, carburization and nitridation environments. In addition to thermal stability characteristics required to prevent thermal distortion and embrittlement, it exhibits excellent stress-rupture strengths. These characteristics, along with a high resistance to carburization and cyclic oxidation, make this alloy the material of choice for many severe applications including ID-finned pyrolysis tubing in high-severity ethylene furnaces.
