Vacuum Carburizing

  • 70" deep, by 70" wide, by 84" high work zone
  • Up to 10,000 lb. total load capacity
  • Advantages of Vacuum Carburizing
  • -Eliminates surface intergranular oxidation
  • -Excellent case uniformity for complex geometries
  • -Precise, alloy-specific process controls result in highly repeatable case depth control
  • -Case depth and carbon content can be closely controlled

Vacuum/Ion Nitriding Department

  • Loads to 48" long & 4,000 lb.
  • Ten vacuum furnaces
  • Pressure gas quenching to 10-bar (nitrogen and argon)
  • Coming online summer 2014: 12-bar
  • Pulse Plasma Ion Nitriding
  • Four hydrogen atmosphere belt furnaces
  • Deep Cryogenic Processing
  • Aerospace & military certified (nitrogen & argon)
