GSL heat treatment: Annealing and tempering by the experts.

Comprehensive service for individual materials


GussStahl Lienen is your experienced partner for all common heat treatment processes. Our heat treatment processes improve the properties of the materials so that the castings are optimally prepared for their specific loads.

Water, hardening oil and air quenching are available as hardening media. The result of the heat treatment is verified by hardness testing and by proving the mechanical technological properties by means of tensile testing and notched bar impact testing. On request, the tests can also be carried out at high or low test temperatures. Our heat treatment processes are subject to regular control by external test equipment monitoring and detailed documentation.



GSL heat treatment – our processes:

  • Diffusion annealing
  • Normalising annealing
  • Soft annealing
  • Stress relief annealing
  • Tempering (hardening and annealing)
  • Annealing of austenitic steel with quenching
  • Annealing treatment under atmosphere or inert gas
