Tempering/Stress Relief/Annealing


Tempering

Tempering is a low temperature heat treatment process normally performed after a hardening process in order to reach a desired hardness or touchness ratio.

 

Annealing

Annealing is used to induce ductility, soften material, relieve internal stresses, and refine the structure by making it homogeneous.

 

Soft Annealing

A high temperature heat treatment process performed with the aim to which is to make a material as soft as possible. 

 

Stress Relieving

Heating a steel object to a suitable temperature, holding it long enough to reduce residual stresses, and then cooling it slowly enough to minimize the development of new residual stresses.
