Tajikistan Nm500 Wear Resistant Steel Plate

Wear resistant steel plate refers to a special sheet product specifically designed for use under conditions of extensive wear and tear. The commonly used wear-resistant steel plate is a plate product made by overlaying a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. In addition, there are cast wear-resistant steel plates and alloy quenched wear-resistant steel plates.

Product Description

The 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 to 1/2 of the total thickness. During operation, the matrix provides comprehensive properties such as strength, toughness, and plasticity to resist external forces, while the alloy wear-resistant layer provides wear resistance that meets the specified working conditions.
The wear-resistant layer of the wear-resistant steel plate alloy is metallurgically bonded to the substrate. By using specialized equipment and automatic welding technology, high hardness self-protection alloy welding wire is uniformly welded onto the substrate, with a composite layer of one to two or even more layers. During the composite process, uniform transverse cracks appear due to different alloy shrinkage ratios, which is a significant feature of wear-resistant steel plates.

The wear-resistant layer of the alloy is mainly composed 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 fibrous form, and the fiber direction is perpendicular to the surface. The microhardness of carbides can reach HV1700-2000 or higher, 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. They can be used normally within 500 ℃.
The manifestations of the wear-resistant layer include narrow channels (2.5-3.5mm), wide channels (8-12mm), curves (S, W), etc; Mainly composed of chromium alloy, with the addition of other alloy components such as manganese, molybdenum, niobium, nickel, boron, etc. The carbide in the metallographic structure is distributed in a fibrous form, with the fiber direction perpendicular to the surface. The carbide content is 40-60%, the microhardness can reach HV1700 or above, and the surface hardness can reach HRC58-62.
Wear resistant steel plates are mainly divided into three categories: universal, impact resistant, and high-temperature resistant; The minimum total thickness of wear-resistant steel plate can reach 5.5 (2.5+3) mm, and the maximum thickness can reach 30 (15+15) mm; Wear resistant steel plates can be rolled into wear-resistant pipes with a minimum diameter of DN200, and can be processed into wear-resistant elbows, wear-resistant tees, and wear-resistant variable diameter pipes.

Product Application
