Heat treatment (Traitement thermique)

Heat treatments allow the structure of the material to be changed to achieve the required hardness properties. FELLER SA carries these treatments to specialist partners.

In most cases, tempering is necessary for several reasons:

  • reducing mechanical wearing

  • creasing the useful life

  • avoiding problems of deformation during assembly

  • guaranteeing functionality (for example for test points)

The structural hardening of steel is obtained by heating the parts to a temperature of between 800 and 1000°C, and then quickly cooling them. This treatment makes the steel harder, but also more brittle. To achieve a good compromise, parts are heated a second time to a certain temperature that depends on the desired hardness. This stress relief is called "tempering".
