A588 grade steel plates (A, B, K) are weathering steels in the material category of high-strength low-alloy structural steels resistant to atmospheric corrosion.
A588 grade B steel plate is suitable for welding, riveting or bolting high strength low alloy structural type. A588 grade B steel plates are mainly used for welding bridges and buildings, which is very important in reducing weight or increasing durability. In most environments, the atmospheric corrosion resistance of A588 grade B steel plate is much better than that of carbon structural steel with or without copper addition.
The executive standard of A588 grade B steel plate is ASTM A588/A588M The delivery state of A588 grade B steel plate is hot rolled, normalized, tempered, normal + back, quenched and tempered. Different delivery states can be selected according to different needs.
During rolling, the A588 grade B steel plate forms a protective layer on the surface of the metal substrate through alloying of Cu, P, Cr, N, etc., so that the A588GrB steel plate has high atmospheric corrosion resistance.
