Astm A588 Grade A Steel Plate Steel Sheet Stock

A588 Grade A is a high-strength low-alloy steel resistant to atmospheric corrosion in the American standard ASTMA 588/A588M-05.

The alloying elements in this steel include Si, Mn, Cr, Ni, Cu, V, etc. The addition of V can play a role in grain refinement and precipitation strengthening, and other elements are solid solution strengthening.

The addition of these elements, while improving the strength of the steel, also deteriorates the weldability of the steel. The steel is alloyed by adding Cu element to improve atmospheric corrosion resistance. The content of Cu is high, reaching 0.32%, and Cu element is an element that is easy to cause welding hot cracks.

A588GrB, A588GrA, A588GrC manufacturing plants, general construction and various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, and various cranes for mines and various engineering constructions , coal mine hydraulic support and other mechanical equipment and other structural parts.

8mm~200mm thick A588 series high weather-resistant bridge structural steel plates include A588GrA, A588GrB, etc. This type of steel forms a protective layer on the surface of the metal substrate through the alloying of Cu, P, Cr, Ni, etc., so it has high atmospheric corrosion resistance. This type of steel is widely used in various weather-resistant building structures (especially for industrial atmospheric environments), bridge auxiliary structures, etc.
