ASTM A276 UNS N08700
ASTM A276 UNS N08700 is a material grade specification for cold-finished or hot-finished bars in N08700 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Boltport uses N08700 bar stock to ASTM A276 specifications for manufacturing stainless steel N08700 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 N08700 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
