ASTM A588 Corrosion Resistant Structural Steel Plate

Weather-resistant structural steel is atmospheric corrosion-resistant steel, which belongs to low-alloy high-strength structural steel. According to its main characteristics, it is divided into high weather-resistant structural steel and weathering steel for welded structures. 1. High weathering steel High weather resistance structural steel is to add a small amount of copper, phosphorus, chromium and nickel elements to the steel to form a protective layer on the surface of the metal collective to improve the atmospheric corrosion resistance of the steel, and a small amount of molybdenum, niobium, Vanadium, titanium, zirconium and other elements are used to refine the grains, improve the mechanical properties of the steel, improve the strength and toughness of the steel, reduce the brittle transition temperature, and make it have better resistance to brittle fracture.
