B-HARD400 Wear Resistant Steel Plate

PRODUCT DESCRIPTION

Wear-resistant Steel plates for construction machinery. Wear-resistant Steel Plate is composed of low-Carbon Steel Plate and alloy wear-resistant layer. The alloy wear-resistant layer is generally 1/3~1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against 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 alloy wear-resistant layer and the substrate. Through special equipment and automatic welding process, the high-hardness self-shielding alloy welding wire is evenly welded on the substrate, and the number of composite layers is one to two or even multiple layers. During the compounding process, due to the different shrinkage rates of the alloys, uniform transverse cracks will appear. This is a remarkable feature of wear-resistant Steel Plates.

Wear-resistant steel plate has high wear resistance and good impact resistance. It can be cut, bent, welded, etc., and can be connected with other structures by welding, plug welding, bolting, etc., saving on-site repair time. Widely used in metallurgy, coal, cement, electric power, glass, mining, building materials, bricks and tiles and other industries. Compared with other materials, it has higher cost performance and is favored by more and more industries and manufacturers.

The alloy wear-resistant layer is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are added at the same time. The carbides in the metallographic structure are distributed in fiber form, and the fiber direction is perpendicular to the surface. The microhardness of cemented carbide can reach above HV1700-2000, and the surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good oxidation resistance, and can be used normally within 500 °C.
The wear-resistant layer can be represented by narrow track (2.5-3.5mm), wide track (8-12mm), curved track (S, W), etc.; it is mainly composed of chromium alloy, and manganese, molybdenum, niobium, nickel and boron are added at the same time . Like other alloy components, the carbides in the metallographic structure are distributed in fiber 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.
