As the boiler steel plate sa588 & a572 steel company is working under medium temperature (below 350 ℃) and high pressure, the boiler steel plate is not only subjected to high pressure, but also subjected to impact, fatigue load and water and gas corrosion. The performance requirements for boiler steel mainly include good welding and cold bending performance, certain high temperature strength, alkali corrosion resistance, oxidation resistance, etc.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the sa588 & a572 steel company 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 sa588 & a572 steel company quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
