B480GNQR hot-rolled weathering steel is also an alloy steel and can be used without painting. If exposed to the weather for several years, it will form a stable rust-like appearance. Compared with other steels, B480GNQR has stronger atmospheric corrosion resistance.
B480GNQR steel is to add a certain amount of Cu, P, Cr and other alloy elements to promote the formation of a protective oxide film on the surface of the product and improve the corrosion resistance of the steel in the atmosphere. These alloying elements can form a dark brown oxide coating on the metal, which can effectively resist the corrosion of rain, snow, ice, and inhibit deeper penetration to enhance the corrosion resistance of B480GNQR, and it does not require painting and anti-rust maintenance.
B480GNQR hot-rolled weathering steel application: mainly used for manufacturing containers, rail vehicles, environmental protection equipment, decorative sculptures, curtain walls, engineering machinery, steel structures, structural welding manufacturing and decoration.
The
chemical composition of B480GNQR weathering steel including copper, nickel, phosphorous and other chemical elements is only a few percent. Don’t underestimate these few percents. It is because of them that the mechanical properties and corrosion resistance of B480GNQR weathering steel can be further improved. Strengthen. Therefore, B480GNQR steel is used for shipping containers, containers, bridges and train tracks.
