Wear-resistant steel is smelted in electric furnaces or converters, and most of the products are castings. In recent years, hot processed materials such as forging and rolling are increasing. The production method of wear-resistant 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 quantity, 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.
