ASTM A276 / A276M UNS S20100

ASTM A276 UNS S20100 is a material grade specification for cold-finished or hot-finished bars in S20100 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Ferrobend uses S20100 bar stock to ASTM A276 specifications for manufacturing stainless steel S20100 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 S20100 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
