SA588 Gr A steel plate chemical composition and mechanical properties

SA588 Gr A steel plate belongs to weathering steel, which has strong corrosion resistance. Because of SA588 Gr A steel plate chemical composition, they show higher atmospheric corrosion resistance than other steels. This is because SA588 Gr A steel plate forms a protective layer on its surface under the influence of weather.
