Process Innovations: Lower Pressure Vacuum Carburizing and Vacuum Nitriding

Chigago, Illinois - Low Pressure Vacuum Carburizing (LPVC) is a specialized, highly technical process pioneered by Solar Atmospheres designed to increase fatigue life and improve wear properties of your parts.  The case hardened surface is supported by a ductile, shock-absorbing core capable of withstanding high load bearing applications.  LPVC produces a uniform, high-quality case with minimized distortion and absence of Intergranular Oxidation (IGO), reducing or eliminating expensive post heat treating machining operations.

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°F – 1200°F preserves the mechanical properties of the base material and minimizes distortion of the finished parts.
