Heat treatments

Heat treatments of steels, particularly stress-relieving treatments, have attracted considerable interest in recent years from mechanical and metallurgical companies, due to the added value they give to manufactured products in terms of quality and reliability.

There are mainly two ways of carrying out heat treatments:

In addition, there is the controlled-atmosphere heat treatment system.

This differentiation depends on the extent of the part of the product to be treated, whether its entirety or only a limited area (usually a weld). Of course, the execution method is also influenced by the condition of the piece, for example when the part to be treated cannot be transported or removed.

Then, depending on the types of steel and the characteristics the customer wishes to obtain, heat treatments can even reach temperatures of 1200 °C.

In addition to the traditional stress-relieving heat treatments, Centrotest srl also performs:

  • Solution annealing heat treatments
  • Normalizing heat treatments
  • Ferritizing heat treatments
  • Quenching and tempering heat treatments
  • Annealing heat treatments
  • Ageing heat treatments
  • Heat treatments on cast pieces (cast iron, aluminium, etc.)

Temperature monitoring is carried out from a control room, with the aid of instrumentation operated by Level III qualified personnel, and with thermocouples calibrated according to the regulations in force.

At the end of each process, the relevant treatment certification will be issued, with the diagram of the measurements obtained from the monitoring and recording devices attached.
