HEF Groupe's CLIN technologies, for Controlled Liquid Ionic Nitriding, include a wide range of Salt Bath Nitriding brand names such as TUFFTRIDE®ARCOR®TENIFER®MELONITE® and QPQ®.

These treatments concern mainly ferrous alloys (steel, cast iron, stainless steel, etc.) and are carried out between 500°C and 630°C, in order to improve the surface properties, such as:

  • Increased wear resistance

  • Good friction properties

  • Excellent seizure resistance

  • Excellent corrosion resistance

  • Good mechanical resistance

  • Resistance to heat over 500 degrees celcius

  • Cosmetic appearance

Among the world, these processes have proven their reliability to:

  • Decrease the production costs, by increasing the toolings lifetime

  • Replace others conventional heat treatments solution (Case hardening, Induction quenching, etc...)

  • Replace others kind of coatings (Hard Chromium, Chemical Nickel, etc...)
