ASTM A276 UNS S32053
ASTM A276 UNS S32053 is a material grade specification for cold-finished or hot-finished bars in S32053 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Boltport uses S32053 bar stock to ASTM A276 specifications for manufacturing stainless steel S32053 bolts, nuts, screws, studs, threaded rods, other fasteners and bar stock components for general engineering purposes.
ASTM A276 specification covers requirements such as chemical composition, mechanical properties, heat treatment and other supplementary requirements for S32053 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
