Vacuum Gas/Oil Quenching Furnace

Vacuum gas/oil quenching furnace
Vacuum Gas / Oil Quenching Furnaces mainly used to process critical parts of aerospace, defense, ordinance factories components, and also for industrial applications.
Vacuum oil / gas quenching is playing a significant role in heat treating applications. Now, these vacuum based oil / gas quenching processes have gained large popularity, and important advantages in a large number of heat treating applications.

Vacuum oil quenching technology is environmentally friendly and offers advantages such as:

  • Superior control of surface chemistry compared to salt bath or controlled atmosphere processes.
  • Ability to harden thick sections and heavy loads in a wide variety of steels.
  • Ability to process finished surfaces without decarburization, so parts processed by vacuum oil quenching do not require plating or protective coatings.
  • Our vacuum oil quench furnaces can be equipped with an optional gas quench capability.
