ASTM A182 / A182M F68

ASTM A182 F68 is a forging material specification for 68 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 F68 specification.

ASTM A182 specification covers requirements such as chemical composition, mechanical properties, heat treatment and other supplementary requirements for 68 stainless steel forgings and forged products.
