Heat treatment of metals

ErreDue S.p.A. produces Nitrogen generators and Hydrogen generators, of all sizes and purity level as well as ancillary gas treatment systems valid for all applications in the thermal treatment of metals.


The heat treatment of metals produces mechanical and structural changes to the material properties by variation of temperature, consisting of heating, soaking and cooling at controlled speed and timing in electric or combustion ovens.

During heating and cooling process, it’s crucial to avoid any metal oxidation that may affect brightness and mechanical properties of the finished parts.


The extremely pure Nitrogen produced by SATURN generators ensures full protection, while the Hydrogen removes any existing oxidation on the metal by reacting (redox) and transforming it into water vapour that is then vented out by the gas itself.


- Higher brightness of the pieces

- Improved mechanical properties
