A588GrB, A588GrA, A588GrC manufacturing plants

A588 GR A is a high-strength low-alloy steel that is resistant to atmospheric corrosion in the American standard ASTMA 588/A588M-05. As alloying elements in this steel, there are Si, Mn, Cr, Ni, Cu, V, etc. The addition of V can play the role of grain refinement and precipitation strengthening, and other elements are solid solution strengthening.

The addition of these elements not only improves the strength of the steel, but 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, various types of cranes for mining and various engineering construction , Coal mine hydraulic support and other mechanical equipment and other structural parts. 8mm~200mm thick A588 series high weathering 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 that it has high atmospheric corrosion resistance. This type of steel is widely used in various weather-resistant building structural parts (especially for industrial atmospheric environments), bridge auxiliary structural parts, etc.
