Key Features:

• The Gases are:  Nitrogen - Cost-effective and widely available gases. Helium & Argon- The best cooling rates available and thus require great accuracy.
• Advantages of Gas Quenching Over Liquid Quenching: Distortion and cracking, for example, when treated thin or complex components, are minimized. Oxidation and surface development are reduced, eliminating or minimizing the need for post-quench cleanup. Better process control permits the same hardness and mechanical properties to be achieved.
• Applications: Aerospace and automotive industries, tool manufacturing. Steels, titanium alloys, and nickel-based superalloys used.

Gas quenching is much more modern controlled than liquid quenching in that it provides high-quality hardened components with much less risk of warpage or surface degradation.
