Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the S690QL carbon equivalent steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the S690QL carbon equivalent steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the S690QL carbon equivalent steel sheet on the truck Good luck.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S690QL carbon equivalent 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 S690QL carbon equivalent quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
