Vacuum Nitriding Services

Increase Part Performance and Service Life

Vacuum nitriding services from Solar Atmospheres can significantly increase the fatigue strength and service life of your parts.  Benefits include  case depths up to 0.025” and improved wear and anti-galling properties due to a 40 – 70% increase in surface hardness.  Corrosion resistance is increased through nitrogen-enrichment.  A controlled low processing temperature of 700 – 1200°F preserves the mechanical properties of the base material and minimizes distortion of the finished parts.
