In recent decades, the development and application of low- and medium-alloy wear-resistant steels have developed rapidly. Because these steels have good wear resistance and toughness, the production process is relatively simple, the overall economy is reasonable, and it is suitable under many working conditions. , welcomed by many users. In order to meet the needs of the development of mining machinery and engineering machinery, high hardness wear-resistant steel was developed. Wear-resistant steel is the largest amount of wear-resistant materials available today. It is a general term for steel materials with high wear resistance. Wear-resistant steel is smelted by electric furnace or converter, and most of the products are cast. There are many types of wear-resistant steel, which can be generally divided into high manganese steel, medium and low alloy wear-resistant steel, chrome molybdenum silicon manganese steel, gas corrosion resistant steel, wear resistant steel and special wear resistant steel. Some common alloy steels such as stainless steel, bearing steel, alloy tool steel and alloy structural steel are also used as wear-resistant steel under certain conditions. Because of their convenient source and excellent performance, they are also used in the wear-resistant steel. a certain proportion. Wear-resistant steel is widely used in mining machinery, coal mining and transportation, engineering machinery, agricultural machinery, building materials, electric machinery, railway transportation and other departments.
