Vacuum Gas/Oil Quenching Furnace

Vacuum Gas/Oil Quenching Furnace
Product Details

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.
