Heat treatment

All kinds of heat treatment (normalization, soft annealing, isothermal annealing, dissolving, stress-relief annealing, hardening treatment) are carried out in our company except from termo-chemical processes. Heat treatment of forgings is carried out in electric and gas fired furnaces with oil and water bath for quenching and tempering. All furnaces for heat treatment are equipped with automatic temperature control, measuring and recording instruments.
