In the production of nail-making equipment, whether it is manufacturing parts or manufacturing tools, we must first know what materials are used and the properties of these materials. Because only after understanding the properties of the material can we determine the processing method, choose the tool material reasonably, and heat the material. The purpose is to change the structure of the material, thereby changing the performance of the material to meet the requirements of processing and use. The performance of metal is mainly divided into two aspects: use performance and process performance. The so-called use performance refers to the properties and adaptability of the material in use, such as physical properties, chemical properties and mechanical properties. The so-called process performance refers to the adaptability and difficulty of metal during processing. According to the processing method, it can be divided into casting performance, pressure processing performance, welding performance, cutting performance and heat treatment performance.
