Tempering is possible because of the instability of the martensite, the principal constituent of hardened steel.

The trunnion journal (22) is made by cutting hardened steel with using no cutting fluid.
Tempering. This is the process of heating quenched and hardened steels and alloys to some temperature blow the lower critical temperature to reduce internal stresses set-up in hardening.

This was a piece of German-hardened steel.
To reheat hardened steel or hardened cast iron to some temperature below the eutectoid temperature for the purpose of decreasing hardness and increasing toughness.
The final structure obtained from tempering a fully hardened steel is called tempered martensite.
