Vacuum Gas Nitriding

This process is performed in a furnace similar to vacuum heat treatment furnaces, but it operates at a lower temperature and does not require quenching. The elimination of quenching from the vacuum nitriding process helps minimize distortion in the parts.

Vacuum Nitriding Benefits

Vacuum nitriding can increase the fatigue strength and service life of your parts. Here are several other benefits:

  • Can achieve case depths up to 0.5″
  • Enhanced wear and anti-galling properties due to a 40–70% increase in surface hardness
  • Increased corrosion resistance due to nitrogen enrichment
  • Uniform coloration

Vacuum Nitriding Applications

Common applications of precision controlled vacuum nitriding are transmission components, gears, tools, and molds. Materials that respond well to vacuum nitriding include:

  • Alloy Steels
  • Specialty Steels
  • Titanium Alloys
  • Stainless Steels
  • Powdered Metals
