A588 Grade B steel

A588 Grade B steel 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.

A588 Gr.B steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness.

A588 is suitable for many applications in the unpainted condition. The atmospheric corrosion resistance of A588 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition when properly exposed to the atmosphere.
