Heat treatment
We carry out the heat treatment in 12 gas furnaces and four quenching tanks. The technological process is computer-controlled and documented by heat treatment records.
Main types of heat treatment
- annealing
- normalisation
- soft annealing
- stress relieving
- solution annealing
- homogenisation, simulated annealing
- quenching of carbon and alloy steels
- quenching of tool steels at an austenitization temperature of 1,100 °C
- quenching of special steel
