The importance of heat treatment for precision metal processing

Precision metal processing in the common processing technology has a lot of, such as: forging, heat treatment, surface treatment, these processes are in order to make the precision parts more practical.

Heat treatment includes three stages: heating, insulation and cooling.The main factors at work in heat treatment are temperature and time.

Heat treatment is to heat the steel in the solid state to a certain temperature, for the necessary insulation, and at an appropriate rate of cooling to room temperature, in order to change the internal structure of the steel, so as to obtain the desired performance.

In the precision hardware processing, the heat treatment is to improve the mechanical function of the mechanical parts, to ensure that the processing quality meets the use needs of the goods.

The importance of precision metal processing heat treatment is as follows:

1. The purpose is to change the internal structure of the steel to improve the performance of the steel.

2. Proper heat treatment can significantly improve the mechanical properties of steel and prolong the service life of machine parts.

3. The heat treatment process can not only strengthen the metal materials to fully tap the potential of material properties, reduce the structural weight, save materials and energy, but also improve the quality of mechanical products, significantly extend the service life of machine parts.

4. Proper heat treatment process can eliminate all kinds of defects caused by casting, forging, welding and other hot processing processes, refine grain, eliminate segregation, reduce internal stress, and make the steel structure and performance more uniform.
