Wear-resistant steel plate is a specially designed plate product, which is mainly used in industrial and mining conditions that withstand large-area wear and tear. It is usually made of low-carbon steel or low-alloy steel with good toughness and plasticity, and is compounded with a layer of alloy wear-resistant layer with high hardness and excellent wear resistance by surfacing welding method on its surface. This composite layer provides higher wear resistance, while the substrate provides a combination of strength, toughness, and plasticity to resist external forces. Wear-resistant steel plates have high hardness, high strength and excellent wear resistance, impact resistance and corrosion resistance, and can maintain a long-term service life in complex working environments.
The surface of wear-resistant steel plates is usually hardened by heat treatment or quenching and tempering processes to further improve their wear resistance and extend their service life. These sheets can be made in a variety of shapes and sizes to suit specific applications and can be processed by cutting, bending, welding, and more. Wear-resistant steel plates have a wide range of applications in industrial production, such as mining, building materials, electric power, chemical industry and other fields.
The model number of the wear resistant steel plate usually starts with nm and is followed by numbers that represent the average Brinell hardness of the material, for example nm400 represents the wear resistant steel plate with an average Brinell hardness of 400HBW. The production process of wear-resistant steel plate includes quenching, tempering, surface treatment, etc., which requires strict control of the composition, microstructure, and mechanical properties of the steel to ensure its stable performance.
