4. Brief introduction of A588M Gr (A, B, K) steel plate: a protective layer is formed on the surface of the metal substrate, so that it has high atmospheric corrosion resistance.

Five, performance characteristics

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.

6. It is used for manufacturing workshops, general construction and various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, various cranes, 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.
