Long-term-high temperature stability of alloy 803 in the chemical process industry
- Special Metals Corp., Huntington, WV (United States)
Alloy 803 is used in the chemical process industry for its high temperature strength and corrosion resistance. Knowledge of the microstructural characteristics as a function of time and temperature are essential for accurate rationalization of mechanical property performance under actual service conditions. This paper seeks to determine the microstructure of alloy 803 as a function of time and temperature for times up to 34,000 hours and temperatures ranging from 595 C to 1095 C. Post-exposure room temperature tensile data are also presented as an indication of the alloy`s tolerance to downtime strains. Intermediate temperature mechanical strength can be attributed primarily to gamma prime ({gamma}{prime}) and higher temperature strength to M{sub 23}C{sub 6} content.
