How it works

Step 1

Place parts in furnace and attach thermocouples directly to hardware.

Step 2

Pull a vacuum on the furnace to ensure clean processing of parts.

Step 3

Heat furnace to appropriate temperature profile to ensure properly heat treated parts.
Vacuum heat treating is clean, easy to control, and safe. The results are clean, shiny parts with minimal distortion and which require comparatively little post-treatment finishing and cleaning.

Benefits of Vacuum Heat Treating

  • Virtually eliminates oxidation problems by performing the operation in a vacuum atmosphere
  • Precisely control heat-up and quench rates to minimize heat-induced distortion
  • Produce full hardness in steels by easily changing cooling rates, even within a single cycle, to enable gas-quenching operations
  • Does not produce toxic or combustible waste gases, making it safer and more environmentally friendly than many liquid-quenching processes
