Description
Incoloy 803
INCOLOY®alloy 803 (UNS S35045), an iron-nickel-chromium alloy, is designed for use in petrochemical,chemical and thermal processing applications. Thenickel and chromium contents of alloy 803 are higherthan those of INCOLOY alloys 800H and 800HT®. Theratios of nickel, iron and chromium are balanced toprovide optimum properties in the temperature range of1550°F (840°C) to 2100°F (1150°C). Alloy 803 is acost-effective material which provides an exceptionallevel of high-temperature corrosion resistance inoxidation, sulfidation and carburization environments.
