HEAT TREATMENT SHOP

JSC "KMZ" Izhora-Metal" carries out heat treatment of the products made from the following alloys:

  • carbon steel
  • alloy steel
  • tool steel
  • corrosion resistant steel
  • heat-resistant steel
  • "АБ', "АК"-steel
  • titanium- and copper-based alloys.

Heat treatment is carried out under the supervision of highly qualified specialists, who have extensive practical experience and are able to offer the best technical solutions.

Heat Treatment Processes
  • quenching and tempering
  • normalization
  • austenization
  • annealing
  • post-weld heat treatment of welded structures for stress relieving.

Modernization of heat treatment shop, namely the installation of 7 new heat treatment furnaces with the use of modern refractory materials, advanced burners by Kromschröder (Germany) in combination with Siemens automatics and electronics, allowed to achieve a minimum temperature difference (± 5°C) for heat treatment operations with the heating temperatures up to 1100°C.
