Introduction to the characteristics of steel with good performance

It is mainly used for large-area wear conditions. It has good performance in terms of toughness and plasticity. The use of surfacing technology can increase the thickness and hardness of the product, because it uniformly welds the high-hardness self-protected alloy wire during welding. on the substrate. The number of composite layers is from one layer 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 has its presence in metallurgy, coal, cement, electricity, glass, mining, building materials, brick and other industries. 

It has good impact resistance, can withstand bending, cutting and welding, and can be connected to other structures by welding, plug welding, bolt connection, etc.

The material is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are also added. In the metallographic structure, the carbides 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. Good oxidizability and stability.
