ASTM A182 F23
ASTM A182 F23 is a forging material specification for F23 grade alloy steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service. Boltport Fasteners offers forged bolts, screws, nuts, studs, threaded rods and similar fasteners or bolting parts in astm a182 f23 specification.
ASTM A182 specification covers requirements such as chemical composition, mechanical properties, heat treatment and other supplementary requirements for F23 alloy steel forgings and forged products.
