S690QL steel material production sheet stockist in China

The working pressure of high pressure boiler steel tube is generally above 9.8 MPa, and the working temperature is between 450℃ and 650℃. The materials of high pressure boiler steel tubes are: 20G, 20MnG, 25MnG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, 12Cr2MoWVTiB, 10Cr9Mo1VNb, SA210A1, SA210C, SA213 T11, SA213 T12, SA213 T22, SA213 T23, SA213 T91, SA213 T92, ST45.8, 15Mo3, 13CrMo44, 10CrMo9-10, S690QL steel material production and so on.

Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of S690QL steel material production, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S690QL steel material production 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 steel material production quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
