AR400 AR450 AR500 wear-resistant steel plate

AR400 AR450 AR500 wear-resistant steel plate is composed of a low-carbon steel plate and an alloy wear-resistant layer. The alloy wear-resistant layer is generally 1/3 to 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 layer provides wear resistance that meets the requirements of specified working conditions.
 
There is a metallurgical bond between the wear-resistant steel plate alloy wear-resistant layer and the substrate. Through special equipment and automatic welding process, the high hardness self-shielding alloy welding wire is uniformly welded on the substrate. The composite layer has one to two layers or even multiple layers. During the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear. It is a remarkable feature of AR400 AR450 AR500 wear-resistant steel plate.
 
Wear-resistant steel properties
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 fibrous 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 temperature, maintains high hardness, and also has good oxidation resistance. It can be used normally within 500°C.
