ASTM A182 FR
ASTM A182 FR is a forging material specification for FR 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 fr specification.
ASTM A182 specification covers requirements such as chemical composition, mechanical properties, heat treatment and other supplementary requirements for FR alloy steel forgings and forged products.
