Abstract

RA85H is a fully austenitic heat-resistant alloy modified with silicon for resistance to carburization. An addition of aluminum confers good oxidation resistance and improves resistance to sulfidation. The fine grain size of this alloy in the solution annealed condition provides unusual resistance to thermal fatigue in applications where it is subjected to quenching. This datasheet provides information on composition, physical properties, and tensile properties as well as creep. It also includes information on forming, heat treating, machining, and joining. Filing Code: SS-492. Producer or source: Rolled Alloys Inc..
