ADVANCED RESOURCES
TO GUARANTEE THE BEST RESULTS.

Since 1988, Steel Trattamenti Termici (Heat Treatment) has been a benchmark for north-east Italy for the heat treatment and thermo-chemical treatment of mechanical components and dies in tool steels. The key role played by such processes in ensuring the same performance requested by customers, entails extremely high standards of quality and in order to guarantee these, the company relies on highly specialised professional resources and innovative technologies.

The company provides customised solutions, tailor-made processes. This involves not only systems ideal for processing pieces of all dimensions but also a sound and flexible organisation, which, every time, shapes it solutions to meet specific requests, using a unique ability to analyse and assess in order to delineate the guidelines to follow during production.

The treatments performed range from those involving bulk hardening, to improve the mechanical properties of steel right to the core, to surface hardening, in order to improve its tribological properties. The treated pieces are provided with maximum durability and perfectly comply with the required performance profile.

The strict specifications of BÖHLER UDDEHOLM, world leader in the production of special steel, are applied to treatments. Systems engineering is managed and calibrated in compliance with the AMS (Aerospace Material Specifications) 2750 international protocol.

The seamless synchronisation of plant operations with its logistics, made possible thanks to accurate planning and an advanced company set-up, allows Steel Trattamenti Termici to process orders very quickly while scrupulously keeping to the times required for carrying out treatments.

The following treatments are provided:

  • High-vacuum quenching
  • Salt-bath quenching
  • Oil heat quenching
  • Cryogenic treatment
  • Gaseous nitriding
  • Ion nitriding
  • Plasox
  • Case hardening
  • Carbonitriding
  • Solubilization
  • Aging
  • Oxidation
