The purpose of tempering

1. Improve the toughness of spring steel

After solution treatment and quenching, the hardness and brittleness of spring steel will be greatly increased, and tempering can reduce the hardness of steel and improve its toughness and ductility by controlling the heating temperature and holding time.

2. Reduce the hardness of spring steel

Another main purpose of tempering is to reduce the hardness of spring steel, making it more suitable for use in different application environments. High hardness of spring steel can easily lead to fracture and fatigue, and tempering can reduce the incidence of these phenomena and improve the service life of steel.

3. Improve the stability of spring steel

Tempering can make the mechanical properties of spring steel more stable. Once the steel is tempered, its performance will be more reliable and stable, so that it can play a more stable role in practical applications.
