Atmospheric Corrosion Resistance of A588 B Steel

ASTM A588 Grade A and A588 Grade B have strong resistance to atmospheric corrosion, due to the formation of a protective oxide film on the metal surface, A588 weathering steel manufacturer can slow down further corrosion, so it has excellent corrosion resistance than ordinary carbon steel . Both are high-strength low-alloy weathering steels with a minimum yield strength characteristic of 50,000, which can keep costs down by designing lighter sections into the structure.

These steels are primarily designed for unpainted applications where maintenance costs are reduced, such as painting. Since its development, weathering steel has been used in a variety of applications including bridges, railcars, cranes, transmission towers, road poles, chemical plants, factories and true health medical shipbuilding.

A588 is suitable for many applications in unpainted conditions. When properly exposed to the atmosphere, the atmospheric corrosion resistance of A588 is significantly better than carbon steels such as A36 and A572-50 with or without copper additions.
