ASTM A276 / A276M UNS S32506

ASTM A276 UNS S32506 is a material grade specification for cold-finished or hot-finished bars in S32506 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Ferrobend uses S32506 bar stock to ASTM A276 specifications for manufacturing stainless steel S32506 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 S32506 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
