What Is Wear Resistance Steel

What Is Wear Resistance Steel

Abrasion resistant steel is a steel material with strong wear resistance containing chemical elements such as silicon, manganese, chromium, copper, vanadium and so on.

Production process of wear resistance steel

Wear resistance steels are all smelted by electric furnaces or converters, and most of the products are castings. In recent years, hot-worked materials such as forging and rolling are increasing. The production method of wear resistance steel parts used in general machinery is not much different from other workpieces, but there should be requirements in terms of heat treatment process or surface treatment process to meet the requirements of ensuring wear resistance. For those steel parts whose material metallurgical purity significantly affects wear resistance, refining measures should be taken, and limit requirements for harmful impurities and gases should be put forward. The number, shape and distribution of the second phase outside the matrix often have a significant impact on the wear resistance of steel parts. At this time, it is necessary to coordinate the design of the chemical composition of the steel, smelting, thermal processing, heat treatment (including thermomechanical treatment), etc. Consider it in order to achieve the requirements of improving wear resistance from the aspect of metallurgical factors.

Strengthening technology of wear resistance steel

Wear is a process that occurs on the surface of the workpiece, so it is very important to strengthen the surface of the workpiece. The surface strengthening technology of steel has a long history. For example, the carburizing technology can be traced back to the Han Dynasty in China at least two or more years ago, and the carbonitriding process has been recorded in Chinese history books more than a thousand years ago. In recent decades, various surface strengthening technologies and equipment have developed rapidly. Taking necessary surface strengthening and surface modification measures can not only save a lot of raw materials, but also give the workpiece surface layer a variety of special structure and performance of materials so as to obtain the most excellent wear resistance and huge economic benefits. Today, surface strengthening technology has become an important development direction in the research and application of wear resistance steel(including wear-resistant materials).

Process development of wear resistant steel

In recent years, the surface strengthening (wetting) technology of iron and steel materials has developed rapidly, and new technologies and new processes have emerged one after another. Different surface strengthening technologies can be selected for different needs to improve the wear resistance of steel parts under various types of wear conditions. Use cheaper base materials to make workpieces instead of expensive alloy steels. Carburizing, carbonitriding, nitriding and other processes are still the main measures to strengthen mechanical parts. In addition, casting processes such as infiltration and composite casting are also used in the manufacture of wear resistance steel parts.
