HEAT TREATMENT

 

LOW TEMPERATURE HEAT TREATMENT

This treatment method consists on making structure transformations to a metallic part. It improves, inter alia, the hardness and the elasticity. It increases the metal performance and its shaping. Heat treatment is a factor such as polishing or the shot peening, but has a consequence on the state of residual stresses.

 

HIGH TEMPERATURE HEAT TREATMENT

Method used to modify the physical and sometimes chemical properties of a material. Tempering involves plunging a hot material in a colder liquid in order to give new physical properties. Induction heating hardens selected areas. Carbonitriding increases the hardness of the metal surface.

Heat treatment line

  • 1 Hardening furnace
  • 3 Box furnaces
  • 20 Continuous belt-furnaces
