This process refers generally to the heat treatment of a material to optimise its properties in a targeted manner. The intention is to achieve an improvement in strength and resistance to chemicals, a reduction in the stresses within the structure of the material, which arise for example due to machining or also quenching, and ultimately an increase in temperature resistance.

The material properties of plastics are for example optimised by ageing. Tempering takes place depending on the material of the workpiece in question at temperatures below the softening range or crystalline melting range.

Suitable furnace type are for example continuous furnaces or temper-hardening furnaces. A constant temperature and optimal air circulation should be provided inside the furnace during tempering. The workpieces should be exposed to prevent accumulation of heat.

The tempering process makes it possible for the structure of the respective workpiece to be changed e.g. the structure in workpieces consisting of cast iron or the transformation of the crystal structure of thin layers. Tempering is used in the glass and plastics industries and in metal processing.
