There are several ways to improve the quality of high temperature resistant spring

1. Austempering

It is suitable for the spring with small diameter and strong permeability. This method can not only reduce the center change, but also improve the strength and toughness of the spring.

2. Thermomechanical treatment

This treatment method is a combination of deformation strengthening and heat treatment strengthening, which can effectively improve the strength and toughness of spring material.

3. Relaxation treatment

After a long time of working under the external force, the high temperature resistant spring will appear stress relaxation and produce a small amount of permanent deformation, resulting in the reduction of the accuracy of the spring. Therefore, the high temperature spring must be relaxed after quenching and tempering.

4. Shot peening

This is one of the most widely used methods to improve the quality of spring. It can improve the surface quality and strength of high temperature resistant spring. Because in the shot peening process, the spring is in the state of compressive stress, so it can also improve the fatigue strength and service time.
