Tempering Temperature
Tempering is a term historically associated with the heat treatment of martensite in steels to change the microstructure and mechanical properties by holding the steel component isothermally at a temperature below which austenite cannot form. When steel is hardened the as-quenched martensite not only is very hard but also has low toughness.

Tempering
Tempering is a type of heat treatment used to increase the toughness of certain metals, most commonly iron-based alloys like steel. The metal being treated, using this process, is heated under its critical point temperature and then air-cooled. The tempering temperature depends on the application of the metal and the desired outcome.
