Structural application of AR500 wear resistant steel plate

AR500 wear resistant steel plate is a kind of special plate used in large area wear condition. AR500 wear resistant steel plate consists of two parts: carbon steel plate and alloy wear resistant layer. Under normal conditions, the thickness of the alloy wear-resistant layer of AR500 wear resistant steel plate is 1/3-1/2 of the total thickness. The matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the wear resistance to meet the requirements of specified working conditions.

The alloy wear-resistant layer of AR500 wear resistant steel plate is metallurgically combined with the base plate. Through special equipment and automatic welding process, the high hardness self-protection alloy welding wire is evenly welded on the base plate, and the number of composite layers is from one to two or even more. In the process of compounding, uniform transverse cracks may appear due to different alloy shrinkage ratio, which is a remarkable feature of AR500 wear resistant steel plate.

The alloy wear-resistant layer of AR500 wear resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the metallographic structure is fibrous, and the direction of the fiber is perpendicular to the surface. The alloy carbide has strong stability at high temperature, maintains high hardness, and has good oxidation resistance. It can be used normally within 500℃.

AR500 wear resistant steel plate is mainly used in the industrial production fields such as metallurgy, coal, cement, electric power, glass, mining, building materials, brick and tile industries, etc.
