ASME SA588 Grade A Steel

ASME SA588 Grade A is weather resistant steel. When propertly exposed to the atmosphere, SA588 Grade A is suitable for many applications in the bare condition.

ASME SA588 Grade A Steel Delivery Condition: 
Hot Rolled, Cold Rolled, Normalized, Quenched, Tempered, Thermal Mechanical Control Process (TMCP).

ASME SA588 Grade A weather resistant steel  forms a protective layer on its surface under the influence of weather.The layer that protects the surface continuously develops and regenerates when subjected to the influence of the weather. In other words, ASME SA588 Grade A steel oxidizes to form the 'protective' coating.
