ASTM A276 Type 800H
ASTM A276 Type 800H is a material grade specification for cold-finished or hot-finished bars in 800H stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Boltport uses 800H bar stock to ASTM A276 specifications for manufacturing stainless steel 800H 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 800H stainless steel round bars, square bars, hexagon bars and other extruded shapes.
