Steel softening in heat treatment process is annealing.

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

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

Saikumar said:   1 decade ago
Heating the metal below critical temperature and cooling in still air, is tempering which increase toughness and reduces harden ability.

Prashant said:   1 decade ago
This all are used for reducing hardness.

Afrasiyab said:   1 decade ago
Hardened steels are softened by normalizing.

What is the difference between Annealing and Tempering?

Annealing is also used to soften the hardened steel.

Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.

Tempering is to reduce internal stress. Annealing is to soften the material.

Annealing is a process of softening the steel.
