Is it reasonable for EN S420ML steel plates quenching to get martensite

The comprehensive mechanical properties of EN S420ML steel plates, Q345B steel plate are good, the low temperature performance is acceptable, and the plasticity and weldability are good. Q345B steel is used for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads, mechanical parts, building structures, general metal structural parts. Plate Q345B is the most versatile and the most used pressure special steel plate for container.

Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished EN S420ML steel plates steel plates products according to the client needs. Realize the service from product drawings-steel plate procurement-steel plate cutting-steel plate processing EN S420ML steel plates steel plate distribution services, so as to save customers manpower and material resources.

The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. EN S420ML steel plates, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
