ASTM 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.
A588 Grade B steel plate is suitable for many applications in the unpainted condition. The atmospheric corrosion resistance of A588 Grade B steel plate 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.
