EN steel grade S355J2 plates manufacturing plant

15CrMo alloy plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of and 15CrMo alloy plate is obvious and the weldability is poor After welding, local high temperature tempering treatment should be carried out The heat treatment process of 15CrMo alloy plate is as follows: the temperature rise rate is 200°C/h, the temperature is raised to 715°C for 1 hour and 15 minutes, the temperature drop rate is 100°C/h, and the temperature is reduced to 300°C before air cooling,EN steel grade S355J2 plates.

Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. , Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.

EN steel grade S355J2 plates,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.
