A-36 Carbon Structural Steel


A-36 Carbon Structural Steel


ASTM A36 is the most commonly used mild and hot-rolled steel. It has excellent welding properties and is suitable for grinding, punching, tapping, drilling and machining processes. Yield strength of ASTM A36 is less than that of cold roll C1018, thus enabling ASTM A36 to bend more readily than C1018. Normally, larger diameters in ASTM A36 are not produced since C1018 hot roll rounds are used.

ASTM A36 steel plate is the most widely used hot-rolled steel product. As a kind of carbon structural steel product, its relative products are round rod steel, angle bar, and steel sections such as I-Beams, H-beams, angles, and channels. Hot rolled ASTM A36 has rough surface on the final product, it’s easy for further processing like machining.

bolted, riveted or welded construction of bridges, buildings and oil rigs. Used in forming tanks, bins, bearing plates, fixtures, rings, templates, jigs, sprockets, cams, gears, base plates, forgings, ornamental works, stakes, brackets, automotive and agricultural equipment, frames, machinery parts. It is also used for various parts obtained by flame cutting such as in parking garages, walkways, boat landing ramps and trenches.
