ASTM A276 Type 414
ASTM A276 Type 414 is a material grade specification for cold-finished or hot-finished bars in 414 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Boltport uses 414 bar stock to ASTM A276 specifications for manufacturing stainless steel 414 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 414 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
