ASTM A182 / A182M F347

ASTM A182 F347 is a forging material specification for 347 grade stainless steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service. Ferrobend offers forged flanges, fittings, valves bodies, fasteners, plates, bars, rings and similar pressure parts in astm a182 grade F347 specification.

ASTM A182 specification covers requirements such as chemical composition, mechanical properties, heat treatment and other supplementary requirements for 347 stainless steel forgings and forged products.
