A wide range of wear-resistant steel classification, can be divided into high-manganese steel, medium and low alloy wear-resistant steel, silico-manganese-chromium-molybdenum steel, cavitation-resistant steel, corrosion-resistant steel and special steel. Some common alloy steel such as stainless steel, bearing steel, alloy tool steel and alloy steel, are also under certain conditions to use as a wear-resistant steel, because of their convenient source of excellent performance, so the wear-resistant steel used also plays an a certain proportion. Chrome-vanadium-molybdenum-chromium-molybdenum-vanadium high-carbon manganese steel manganese steel used in the manufacture of cement in coarse grinding mill liner when positions showed a higher wear resistance. The chemical composition of these steels and abrasive wear test results in Table 4. Table to the wear resistance of austenitic high manganese steel is 1, compare the relative wear resistance of steel components.

Wear surface hardening technology is in the process of surface, therefore, strengthen the surface is very important. Steel surface hardening technology has a long history, for example, carburizing at least two dry years can be traced back to the Han Dynasty in China, while China's history books a thousand years ago on the carbonitriding process has been documented. In recent decades, a variety of surface enhanced the rapid development of technology and equipment, take the necessary measures for surface hardening and surface modification, not only can save a lot of raw materials, and can give the surface layer of a variety of special, as a whole material is difficult to get the organizational structure and performance, to obtain the most excellent wear resistance and great economic benefits. Today, technology has become resistant surface hardening of steel see (including wear-resistant material) is an important research and application development.
