Wear-resistant steel is smelted with electric furnace or converter, and the products are mostly castings, and in recent years, hot working 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 the heat treatment process or surface treatment process to meet the needs of ensuring wear resistance. For those steel parts whose metallurgical purity significantly affects wear resistance, refining measures should be taken, and limits should be put forward for harmful impurities and gases. In addition to the matrix, the number, shape and distribution of the second phase often have a significant impact on the wear resistance of steel, so it is necessary to consider the chemical composition design, smelting, thermal processing, heat treatment (including thermomechanical treatment) and so on from the aspects of steel, so as to strive to meet the requirements of improving wear resistance from the metallurgical factors.
