Vacuum Nitriding Furnaces


Vacuum nitriding furnaces can be used as vacuum nitriding or vacuum nitrocarburizing for die and mold,mechanical drive medium, gear, shaft and other high precision components.


  • A stainless steel retort
  • Vacuum purging up to 5×10-2 mbars
  • Reactive atmosphere for thermochemical processes like gas nitriding, black oxidizing or nitrocarburizing
  • High internal convection for optimal heat transfer
  • Temperature uniformity is better than ±2 oC
  • Fully automatic control for various recipies

The nitriding process is a chemical reaction, and it’s reasult is determined by temperature, furnace pressure, time and nitrogen potential etc. ingredients. In the past nitrogen control adopts the indirect method of measuring amonia decomposition rate, which have storage of hysteresis and low automatization, but now the Sistem Teknik vacuum nitriding furnaces can solve the problem through importing the H2 sensor from German Stange Company to measure the gas. Also use the high-end program controller to calculate the H2 % and automatically adjust the gas ingredients to reach the Kn balance.
