Abstract

RA 800H is an austenitic iron-base, heat-resistant alloy with excellent high-temperature strength and good resistance to oxidation in air up to 2000 F (1090 C). High creep-rupture properties are obtained by a solution-anneal treatment followed by a rapid cool; grain size is controlled in the range 1 to 5 on the ASTM scale. RA 800H is free from embrittlement by sigma-phase formation. This alloy is well suited for high-temperature processing in refining or petrochemical service. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-373. Producer or source: Rolled Alloys Inc..
