B450NQ material is a low-alloy high-strength atmospheric corrosion-resistant structural steel, which is called weathering steel in China. We supply 3.0mm thickness B450NQ steel sheets from factory direct sale. These sheets are mainly used for steel structures such as railways, vehicles, bridges, towers, etc. that are exposed to the atmosphere for a long time. By alloying Cu, Cr, Ni, etc., and simply adjusting the content of some elements of ordinary low carbon steel (Q235 steel), without changing the production process conditions of Q235 steel, it can produce a good atmospheric corrosion resistance Economical weathering steel with mechanical properties.
3.0mm B450NQ steel sheets use:
When B450NQ weathering steel is used, it can be painted, bare or stabilized. The requirements for painting are the same as ordinary carbon steel. In particular, it should be pointed out that this material can be used without paint, which is the most prominent advantage of weathering steel. In areas where there is no serious air pollution or not particularly humid, weather-resistant steel can be directly exposed to the atmosphere without painting. Generally, after a period of time, the rust layer gradually stabilizes, and corrosion no longer develops. The appearance is a beautiful chocolate color. This kind of steel knot has no problems such as paint aging, and no paint maintenance is required, which greatly reduces the maintenance cost, and of course avoids the losses caused by the influence of paint on use. Because of its unique color, weathering steel is used as a building facade in many countries! Its own characteristics can greatly reduce the corrosion rate of steel plates, making the building easier to maintain, paint-free, and more environmentally friendly during later use.
