Tempering is a heat treatment carried out on steel for freshly tempered parts, with the aim of reducing the stresses produced during temper.

Quenching makes the steel more brittle (with less shock resistance) and creates internal tensions, which is corrected bu tempering which consists of reherating the quenched part at a temperature much lower than that of the quenching (critical zone - austenitic phase).

The tempering temperature and the time it is maintained at this temperature have a decisive influence on the final properties obtained from the steel: the longer the time and/or the higher the temperature, the more ductile the steel will become. The alloying elements of steel also influence tempering, changing its behavior in the process (secondary hardening).

Tempering increases the ductility and elasticity of steel and is used especially in the manufacture of springs.

Tempering is carried out right after quenching to mitigate these negative effects.

Nitroprime is a company specialized in this type of treatment and we seek constant improvement to be increasingly able to provide an excellent service.
