In our shop are installed thermal treatment facilities of wide technological potentials which can ensure high quality in compliance with European standards.
Out Thermal Treatment Shop can offer you the following thermal and chemical-thermal processes:
• Cementation and hardening of low-carbon steels – we can cementate and harden without any deformation your low-carbon non-alloyed and alloyed parts to the required hardness and layer depth;
• High temperature nitriding and carburizing – whenever you have a technological requirement for nitrogen and carbon saturation at high temperature, we can perform this process in our furnaces in controllable atmosphere;
• Full hardening of tool steels – if your tools are working in "hot" or "cold", and are of weight below 220 kg, they can be heat treated by us in protected medium meeting the technological requirements;
• Full hardening of carbon and alloyed steels – we can harden any steel of this class and meet your design and technological requirements with the necessary quality;
• Thermal improvement of steels – we can ensure performance of the process according to your thermal improvement requirements;
• Ageing of hardened steels – if you need to keep sizes of your parts for long time, we can provide ageing for the hardened parts;
• Annealing of workpieces before machining – when you need annealing before machining we will provide the suitable heat treatment for your workpieces.








The equipment of our Thermal Treatment Shop is running in endogas protective atmosphere which ensures heat treatment without oxidizing. All processes such as preparation of the atmosphere, temperature regulation, residence time and other parameters are computer controlled and printout of the process can be obtained on request. The laboratories of Holding Zagora provide control of workpieces, and quantometric and metallographic control when necessary. The maximum weight of the heat treated items is 200÷250 kg.
Working space for accommodation of the heat treated parts is А х В х Н - 600 mm х 900 mm х 450 mm.
Average capacity of equipment:
• hardening and tempering: 110 kg/h
• cementation and hardening: 50 kg/h
• nitrocementation and hardening: 70 kg/h
If necessary we can provide heat treatment for parts around-the-clock.
Our good partners are: M+C Hydraulic; Arsenal; СВМ – Italy and others.
When you do no have heat treatment engineers, we will provide you with advise on the necessary heat processes from highly qualified experts with large experience.
