What is the application scope of Q355NH weathering steel

In the railway manufacturing, vehicle manufacturing, bridge manufacturing and construction, it all needs the steel materials. However, due to the long-term exposure of these buildings to the atmosphere, the use of ordinary steel can not withstand the harsh environment, humidity and moisture in the atmosphere, and can not guarantee the safety of these large buildings. So in these industries, the choice of steel becomes extremely critical. Now in the construction of large outdoor buildings, Q355NH weathering steel has become an indispensable steel.

Q355NH weathering steel not only has good abrasiveness and high temperature resistance of high-quality steel, but also has very good ductility and weldability. At the same time, the weathering resistance of Q355NH weathering steel is also much more than several times higher than that of ordinary steel. Therefore, the use of Q355NH weathering steel is indispensable in the fields of vehicle, harbor construction, oil exploration and container manufacturing.
