B480GNQR hot rolled steel

B480GNQR hot rolled steel is to add a certain amount of alloy elements, such as Cu, P, Cr and so on to promote the formation of protective oxide coating on the surface of the product to improve the corrosion resistance of steel in the atmosphere.

Product Details

Product Advantages

B480GNQR weather resistant steel has a protective layer of rust resistance to atmospheric corrosion, it can be used in the manufacture of vehicles, bridges, towers, containers and other steel low-alloy structural steel.Compared with carbon steel, B480GNQR weather resistant steel has better corrosion resistance in the atmosphere.Compared to stainless steel, only trace amounts of alloying elements, alloys such as weathering resisting steel elements of total phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. is only a few percent.

B480GNQR weathering steel application: mainly used in manufacturing container, railway vehicles, environmental protection equipment, decorative sculpture, curtain wall, engineering machinery, steel structure, structure of welding manufacturing and decoration. To promote the use of various structural parts with a certain corrosion resistance requirements of the manufacture and aesthetic decoration.
