Bengbu carbon steel hook manufacturer (cooling method when carbon steel is normalized)

Heat treatment refers to a metal thermal processing process in which materials are heated, kept warm and cooled in a solid state to obtain the desired structure and properties. Heat treatment is a metal thermal processing process in which metal materials are heated, kept warm, and cooled in a certain medium, and their properties are controlled by changing the metallographic structure on the surface or inside of the material. Sometimes there are only two processes of heating and cooling. These processes are connected with each other and cannot be interrupted. The editor of Demai Transmission will explain to you some knowledge about heat treatment today. Heat treatment process characteristics Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or changes the surface of the workpiece. The chemical composition of the workpiece endows or improves the performance of the workpiece. It is characterized by improving the intrinsic quality of the workpiece, which is generally not visible to the naked eye. In order to make metal workpieces have the required mechanical properties, physical properties and chemical properties, in addition to reasonable selection of materials and various forming processes, heat treatment processes are often essential. steel
