Heat treatment is performed in a computer-controlled furnace. Degreasing of parts prior to hardening is carried out in tri-chlor vapours in a facility with a closed cycle. For all processed parts there is an attest certificate in respect of the hardness test; archiving takes place automatically during the cycle. On request, there is the possibility of conduction metallographic analysis, and/or issuance of a document concerning the heat treatment process.


Vacuum hardening

Heat treatment by hardening, tempering and annealing of structural and tool steels in a vacuum.

Limitations to the size and weight of the processed parts:

  • maximum diameter of the component up to 420 mm (in case of high-speed steel max. Ø 80 mm)
  • maximum length of the component 750 mm
  • maximum weight of the component 100 kg
  • maximum temperature 1200°C
  • quenching medium nitrogen, salt

Hardening in a protective atmosphere

Heat treatment by hardening, tempering and annealing of structural and tool steels in a protective atmosphere.

Limitations to the size and weight of the processed parts:

  • maximum diameter of the component 450 mm
  • maximum length of the component 700 mm
  • maximum weight of the component 200 kg
  • maximum temperature 950°C
  • quenching medium salt, oil
