Product Name: Grade: SS400, EN steel grade S355J2 platesItem:Hot Rolled Medium and Tensile Structural SteelWidth: 1000mm-4500mmThickness:5mm-150mmLength: 3000mm-18000mm

The wear-resistant layer of EN steel grade S355J2 plates wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy EN steel grade S355J2 plates carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

For wear-resistant steel plate, it is not the higher the hardness, the better the wear resistance! Hardness is the basis of excellent wear resistance of EN steel grade S355J2 plates, wear-resistant steel plate, but the relationship between hardness and wear resistance is not in direct proportion. The reason why wear-resistant steel plates are wear-resistant is that they have hard particles and soft matrix. Generally, in the process of wear, there will be some falling substances, which will be incorporated into the soft matrix and will not cause great damage to the surface.
