ASTM A182 F309 is a forging material specification for stainless steel of the 3009 grade, which is utilised in naked forgings, forged and machined products, and other high-temperature applications. Resistant Metal Alloys offers ASTM A182 f309 forged bolts, screws, nuts, studs, threaded rods, and other fasteners and bolting parts.
Chemical composition, mechanical characteristics, heat treatment, and other extra criteria for 309 stainless steel forgings and forged products are covered by the ASTM A182 specification.
