ASTM A182 F61 is a forging material specification for 61 grade stainless steel that is used to make naked forgings, as well as forged and machined products, for high-temperature applications. Astm a182 f61 forged bolts, screws, nuts, studs, threaded rods, and similar fasteners or bolting parts are available from Resistant Metal Alloys.
Chemical composition, mechanical characteristics, heat treatment, and other extra requirements for 61 stainless steel forgings and forged products are covered under the ASTM A182 specification.
