ASTM A182 F53 is a forging material specification for stainless steel grade 53 that is used to make naked forgings, forged and machined products, and other high-temperature applications. Astm a182 f53 forged bolts, screws, nuts, studs, threaded rods, and similar fasteners or bolting parts are available from Resistant Metal Alloys.
For 53 stainless steel forgings and forged products, the ASTM A182 specification covers chemical composition, mechanical characteristics, heat treatment, and various extra requirements.
