Tempering is usually performed after hardening to reduce the excess hardness of only quenching/hardening. The temperature and the time of tempering yield the desired hardness level on a given material. The choice of tempering parameters depends on the material and the industrial application.


  • Reduces the stress after quenching
  • Reduces the brittleness generated by only hardening/quenching
  • Increases material toughness
  • Precise control of the hardness level
