ASTM A182 F51 is a forging material specification for 51-grade stainless steel that is used to make naked forgings or forged and machined products for high-temperature applications. Astm a182 f51 forged bolts, screws, nuts, studs, threaded rods, and similar fasteners or bolting parts are available from Resistant Metal Alloys.
For 51 stainless steel forgings and forged products, the ASTM A182 specification covers chemical composition, mechanical characteristics, heat treatment, and various extra requirements.
