In the process of making wear-resistant steel plate, it is mainly composed of low-carbon steel plate and alloy wear-resistant layer. The wear-resistant layer of alloy is generally 1/3~1/2 of the total thickness. When working, the base body provides comprehensive properties such as strength, toughness and plasticity against external forces, and the wear-resistant layer of the alloy provides wear resistance that meets the requirements of the specified working conditions.
The alloy wear-resistant layer of the wear-resistant steel plate is metallurgically bonded. To a certain extent, through its special equipment, the automatic welding process is adopted to effectively weld its high-hardness self-protecting alloy wire to the substrate uniformly. The composite layer is layered to two layers and to multiple layers. The alloy shrinkage ratio is different, and uniform transverse cracks appear, which is a remarkable feature of wear-resistant steel sheets.
The 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 metallographic structure is fibrously distributed, and the fiber direction is perpendicular to the surface. The microhardness of carbide can reach above HV1700-2000, and the surface hardness can reach HRC58-62. The alloy carbide has strong stability at high temperature, maintains high hardness, and also has good oxidation resistance, and is completely used normally within 500 °C.
