Incoloy 803(UNS S35045), an iron-nickel-chromium alloy, is designed for use in petrochemical,chemical and thermal processing applications. The nickel and chromium contents of alloy 803 are higher than those of INCOLOY alloys 800H and 800HT . The ratios of nickel, iron and chromium are balanced to provide optimum properties in the temperature range of 1550°F (840°C) to 2100°F.
Incoloy803 is a cost-effective material which provides an exceptional level of high-temperature corrosion resistance in oxidation, sulfidation and carburization environments.Incoloy 803 exhibits excellent stress-rupturestrengths at elevated temperatures. These characteristics, along with a high resistance to carburization and cyclic oxidation, make Incoloy803 the material of choice for many severe applications including ID-finned pyrolysis tubing in high-severity ethylene furn.
