ASTM A276 / A276M Type 202
ASTM A276 Type 202 is a material grade specification for cold-finished or hot-finished bars in 202 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Ferrobend offers 202 bars, shafts, angle, channel, beam profiles, bolts, studs, screws, nuts, threaded rods, pins and other bar stock components to astm a276 type 202 specification.
ASTM A276 specification covers requirements such as chemical composition, mechanical properties, heat treatment and other supplementary requirements for 202 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
