Heat treatments


Mainly used in solenoid operated valves and ferritic stainless steel components for a variety of industries, including the automotive industry, this process aims to eliminate residual magnetism due to the structure of the alloy which has been accentuated by mechanical working.

It involves heating the part, holding it at temperature and then cooling it in a controlled manner to obtain the magnetic performance required for the product to operate properly.

The treatment is done in vacuum, and is completely oxidation, decarburisation and carburisation free, so that the finished part can then be worked without altering the magnetic characteristics obtained mechanical processing following the heat treatment itself.


  • Improved magnetic specification
  • Eliminates residual magnetism
  • Effectively complete recrystallisation of the steel
  • Maximally softened material
