Steel softening in heat treatment process is annealing.

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

Tempering is a process in which hardened steel (Martensite) is transformed into soft steel with increase in toughness.

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

This all are used for reducing hardness.

Hardened steels are softened by normalizing.

What is the difference between Annealing and Tempering?
Annealing is also used to soften the hardened steel.
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.
