ASTM A276 / A276M UNS S41500
ASTM A276 UNS S41500 is a material grade specification for cold-finished or hot-finished bars in S41500 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Ferrobend uses S41500 bar stock to ASTM A276 specifications for manufacturing stainless steel S41500 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 S41500 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
