The double-metal composite wear-resistant steel plate

- Sep 03, 2019-

The double-metal composite wear-resistant steel plate is a plate product specially used for large-area wear conditions. It is a combination of a certain thickness of high-strength and resistant to the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity. A plate product made of a wear-resistant layer with excellent abrasion.

The bimetal composite wear-resistant steel plate is composed of a low-carbon steel plate and an alloy wear-resistant layer, and the anti-wear layer generally accounts for 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 layer provides wear resistance that meets the requirements of the specified working conditions.

The wear-resistant steel alloy wear layer and the matrix are metallurgically bonded. The high-hardness self-protecting alloy welding wire is uniformly welded on the substrate by special equipment, and the composite layer is layered to two layers or even multiple layers. During the compounding process, uniform transverse cracks occur due to different alloy shrinkage ratios. This is a remarkable feature of wear-resistant steel.

The wear-resistant layer 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 fibrous, 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.

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