A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness.When properly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition.Equal steel grade of ASTM A588 Grade A, in other standards: EN 10155 :S355J2G1W;SEW 087:WTSt 52-3; UNI:Fe510 D2K1;BS 4360:WR 50 C and some other steel grade.
ASTM A588 Grade A and A588 Grade B are highly resistant to atmospheric corrosion, superior corrosion resistance over regular carbon steel as a result of the development of a protective oxide film on the metals surface which slows down further corrosion. Both are high-strength low-alloy weathering steels which exhibits 50,000 minimum yield strength characteristic allows cost reduction through the ability to design lighter sections into structures.
