Wear-resistant steel plate consists of two parts: low carbon steel plate and alloy wear-resistant layer. The alloy wear-resistant layer is generally 1/3~1/2 of the total thickness. During operation, the matrix provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.

There is a metallurgical bond between the wear-resistant steel plate alloy wear-resistant layer and the base plate. Through special equipment and an automatic welding process, the high-hardness self-protecting alloy wire is evenly welded to the substrate. The number of composite layers is one to two or even multiple layers. During the composite process, due to the different shrinkage ratios of the alloys, uniform transverse cracks appear. This It is a distinctive feature of wear-resistant steel plates.

The alloy wear-resistant layer is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are also added. The carbides in the metallographic structure are distributed in a fiber shape, 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. Alloy carbide has strong stability at high temperatures, maintains high hardness, and also has good oxidation resistance, and can be used normally within 500°C.

The wear-resistant layer is expressed in narrow channels (2.5-3.5mm), wide channels (8-12mm), curves (S, W), etc.; it is mainly made of chromium alloy, while manganese, molybdenum, niobium, nickel, and boron are also added For other alloy components, the carbides in the metallographic structure are distributed in a fibrous form, and the fiber direction is perpendicular to the surface. The carbide content is 40-60%, the microhardness can reach above HV1700, and the surface hardness can reach HRC58-62.

Wear-resistant steel plates are mainly divided into three categories: general-purpose, impact-resistant and high-temperature-resistant types; the total thickness of wear-resistant steel plates can reach a minimum of 5.5 (2.5+3) mm and a maximum of 30 (15+15) mm; wear-resistant steel plates Wear-resistant pipes with a minimum diameter of DN200 can be rolled and processed into wear-resistant elbows, wear-resistant tees, and wear-resistant reducers.
