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


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