It is mainly divided into low alloy welding wear-resistant steel, low alloy wear-resistant steel for engineering machinery parts and low alloy wear-resistant steel for agricultural machinery.
Low alloy welding wear-resistant steel is a type of steel developed on the basis of low alloy high strength welding steel. Japan, the United States, Germany and the former Soviet Union have widely used high strength steel plates with a tensile strength of 590 MP to 785 MPa in the manufacture of wear-resistant parts of mining machinery and engineering machinery. In order to further improve the service life of components subjected to strong wear, low alloy high hardness steel plates have been developed since the 1970 s. This type of steel has high hardness (Brinell hardness can reach HB500) and is weldable. This type of steel is usually made into steel plates or steel sections by rolling, and then welded into components. It is mainly used for the middle trough bottom plate of coal mine scraper conveyors, wear-resistant liners and guard plates of mining machinery, liners for large dump truck buckets, etc. Some steel companies in Japan and other countries have compiled this type of steel into.
