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

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.
