ASTM A276 / A276M UNS S42000

ASTM A276 UNS S42000 is a material grade specification for cold-finished or hot-finished bars in S42000 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Ferrobend uses S42000 bar stock to ASTM A276 specifications for manufacturing stainless steel S42000 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 S42000 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
