Heating the metal below critical temperature and cooling in still air, is tempering which increase toughness and reduces harden ability.

Sagar said:   1 decade ago
Tempering is a process in which hardened steel (Martensite) is transformed into soft steel with increase in toughness.

Tempering means generally atoms are close together its like tightening hence its increase hardness of steel.

Steel softening in heat treatment process is annealing.
