Wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc. Wear resistant steel plate can be connected with other structures by welding, plug welding, bolt connection, etc.. It is time-saving and convenient in the process of maintenance site. Wear resistant steel plate is widely used in metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. Compared with other materials, it has a high cost performance and has been favored by more and more industries and manufacturers.EN steel grade S420NL material

EN steel grade S420NL material,Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
