Spring is an important mechanical part. Its basic function is to convert mechanical work or kinetic energy into deformation energy by taking advantage of the elasticity of materials and the structural characteristics of springs themselves. In restoring deformation, the deformation energy is converted into kinetic energy or mechanical work.

According to the heating and cooling mode and the characteristics of steel microstructure and properties:
Annealing and normalizing are mainly used for preliminary heat treatment, and are considered as final heat treatment only when the workpiece performance requirements are not high.
