ASTM A276 Type 316L Fasteners
ASTM A276 Type 316L is a material grade specification for cold-finished or hot-finished bars in 316L stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Boltport uses 316L bar stock to ASTM A276 specifications for manufacturing stainless steel 316L 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 316L stainless steel round bars, square bars, hexagon bars and other extruded shapes.
