Automobile steel sheet is mainly used to manufacture automobile girders (longitudinal and cross girders), frame and other structural parts. The automobile girder should not only bear heavy static load, but also bear certain impact, vibration, etc., so the steel sheet A588 Gr B steel plate is required to have certain strength and fatigue resistance, as well as better stamping performance and cold bending performance to meet the requirements of cold stamping processing.The development of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with high-quality and efficient services, work together for win-win, and create a better tomorrow!Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the 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 quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.With the increase of temperature, the yield limit of A588 Gr B steel plate will decrease monotonically, but the tensile strength of A588 Gr B steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of . Near the blue brittleness temperature, the A588 Gr B steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel It can provide customers with drawing design, deep processing services and installation solutions 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world The company has won widespread praise from customers,A588 Gr B steel plate.
