Q345GNH steel plate bridge steel features:
Traditional high-strength bridge steel not only has poor impact toughness, weldability, and fatigue properties, but also cannot resist atmospheric and marine environment corrosion. Therefore, the concept of High Performance Steel (HPs) III was proposed abroad. In addition to the high strength of Q345GNH steel plate, the welding performance, low temperature toughness and especially the corrosion resistance of the steel have been greatly improved. Weathering steel is atmospheric corrosion-resistant steel, which is a low-alloy steel between ordinary steel and stainless steel, and its weathering resistance is 2 to 8 times that of ordinary steel. High-performance weathering bridge steel can resist corrosion from industrial atmosphere, acid rain, marine atmosphere and sea water, and can be used without coating for inland and coastal bridges.
