The heat treatment of the damping nut is one of the most important processes in mechanical manufacturing. Compared with other machining processes, heat treatment does not change the shape of the workpiece and the overall chemical composition, but changes the microstructure of the workpiece or the chemical composition of the surface. Workpieces are given and improved in certain performance. And its feature is to improve the quality of the workpiece memory, which is not visible to the naked eye.
In order to enable the damping nut to have certain mechanical, physical, and chemical properties it needs, heat treatment technology is indispensable, in addition to materials and various molding processes that should be reasonable when selected. In particular, steel is the most commonly used material in the machinery industry. Its microstructure is very complex. At this time, the heat treatment process can be used to control. Therefore, the main content of the heat treatment technology of the damping nut is the heat treatment of steel. In addition, when making nuts, other metals can change mechanical, physical and chemical properties through heat treatment to obtain different performance.
