NM500 is a high-strength wear-resistant steel plate with high wear resistance. The Brinell hardness value reaches 500 (HBW), which is mainly to provide protection in the occasions or parts that need wear resistance, so that the equipment has a longer life and reduces maintenance costs. Maintenance and shutdown, correspondingly reduce capital investment. NM500 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 NM500 wear-resistant steel plate alloy wear-resistant layer and the substrate. Through special equipment and automatic welding process, the high-hardness self-protected alloy welding wire is uniformly welded on the substrate, and the number of composite layers is one to two or even multiple layers. During the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear. It is a distinctive feature of wear-resistant steel plate.
The alloy wear-resistant layer 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 fibers, and the fiber direction is perpendicular to the surface. The microhardness of carbide can reach HV1700-2000 or more, 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, and can be used normally within 500 ℃.
