 Advantages of High Pressure Gas Quenching:

• Reduction in geometric change of treated work
• Homogeneous quenching with minimal variation part to part and load to load
• Quenching intensity is adjustable through gas pressure and velocity
• Process flexibility with N2 or He gases
• A dry process - treated surfaces are clean no post treatment is required
• Process controls are computerized insuring reproducible results.
• No residue in blind holes
• Capture and recycling of He gas is cost competitive
