Q355NHE grade is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and E represents quality grade (A, B, C, D, E) composition. Q355NHE is an atmospheric corrosion-resistant steel plate, also called weather-resistant steel plate. It has the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature, and fatigue resistance.
Bridge steel A572 grade 60 high strength steel is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.
The hardness and impact toughness of precipitation-strengthened wear plates, A572 grade 60 high strength steel are also improved. For example, the hardness of the wear-resistant plate after precipitation strengthening is 230-300 HBW, and the impact toughness is 140-180. More importantly, the improvement of the above indicators does not bring about a significant decrease in plasticity. The performance of the wear-resistant plate after water quenching at 1100℃, first holding at different temperatures in the middle temperature zone, and then water quenching at 970℃. With the increase of the holding temperature in the middle temperature zone and the extension of the holding time, the number of carbides in the steel increases, and the precipitation strengthening effect increases, resulting in an increase in hardness.
