Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the Q500NH corten steel sheet quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After Q500NH corten steel sheet quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
The cold working performance of Q500NH corten steel sheet and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of Q500NH corten steel sheet and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate Q500NH corten steel sheet should also have good welding performance and low notch sensitivity. If you want to have a more comprehensive and detailed understanding of bridge steel plate, welcome to visit our official website for consultation.
