Wear-resistant steel plate consists 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 strength, toughness, plasticity and other comprehensive performance to resist external forces. The alloy wear-resistant layer provides wear-resistant performance to meet the requirements of the specified working conditions. Wear-resistant steel plate alloy wear-resistant layer and matrix metallurgical combination.

The alloy wear-resistant layer provides wear-resistant performance to meet the requirements of the specified working conditions.

Wear-resistant steel plate alloy wear-resistant layer is metallurgically bonded with the matrix. Using special equipment and automatic welding technology, the high hardness self-protection alloy welding wire is uniformly welded on the substrate,. The number of composite layers is one to two or even multiple layers. In the composite process, due to the different alloy shrinkage, there will be uniform transverse cracks, which is wear-resistant steel plate.

The wear-resistant layer of the alloy is dominated by chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the metallographic organization is fibrous, and the fiber direction is perpendicular to the surface. The microhardness of the carbide can be up to HV1700-2000 or more. The alloy carbide is stable at high temperatures and maintains a high hardness,. It also has good oxidation resistance and can be used normally within 500℃.

Wear-resistant steel plate applications

Wear-resistant steel plate has high wear resistance and good impact performance,. It can be cut, bent and welded, and can be connected to other structures by welding, plug welding and bolting. The maintenance site process is time-saving and convenient, and it is widely used in metallurgy, coal, cement, electric power, glass, mining, building materials, brick and tile and other industries. It is very good compared with other materials.

In the eyes of professionals, it is not difficult to choose hard surface wear plate, only need to pay attention to the following issues.

1. Understand the basic situation. The main thing is to understand what styles of hard surface wear plate are available on the market, and the performance price of different styles. Provide a basis for purchase.2. Choose a reliable manufacturer. Nowadays, there are many manufacturers that provide customized hardfaced wear plates, and the comprehensive strength of different manufacturers is different, which makes the performance of the products different.

3. Choose a good purchasing channel. There are many kinds of purchasing channels at present, such as contacting manufacturers for customization and purchasing in the wholesale market. Before choosing the procurement channel, we should understand the procurement price of each channel, and try to choose the procurement channel with the same type and the same cladding wear-resistant plate with the lowest quotation.

Of course, there are many other issues to consider when purchasing hardfaced wear plates, such as paying attention to the quality of hardfaced wear plates. If the quality is not good, it will inevitably affect the service life and use effect. Surfacing wear plate is formed by adding special elements, such as silicon and manganese elements, to ordinary steel, which can enhance the wear resistance of the steel plate. Before purchasing, qualified customers can also visit the wear surfacing wear resistant plate manufacturers on the spot to understand their production capacity, scale of operation and industry reputation.
