, A588GrB material is a high-strength low-alloy structural steel in shapes of profiles, plates and bars. Through the alloying of Cu, P, Cr, Ni, a protective layer is formed on the surface of the metal substrate, so that A588GrB steel has a high resistance to atmospheric corrosion. A588GrB high-strength low-alloy steel is widely used in various weather-resistant building structural parts (especially for industrial atmospheric environments), bridge auxiliary structural parts.

Heat treatment specification and microstructure of 12Cr1MoV alloy plate:
Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling. Microstructure: bainite + ferrite.
