Vacuum Nitriding

Precision vacuum nitriding enhances fatigue strength and prolongs part life.

How Does Vacuum Nitriding Work?

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 0.025″
  • Enhanced wear and anti-galling properties due to a 40–70% increase in surface hardness  
  • Increased corrosion resistance due to nitrogen enrichment
  • Controlled low processing temperature of 700–1,200°F preserves the mechanical properties of the base material and minimizes distortion of the finished parts
  • 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
