High Pressure Gas Quench

ALD-Holcroft offers high pressure gas quenching (HPGQ) capabilities for deployment in all of our equipment.  We provide pressures from 2 to 20 bar as required by the user.  Naturally quench media (gas) is a consideration in choosing gas quench and this is typically not just a users choice, but a critical demand of the materials being processed.  The Jominy Curves (see left) provide a means to estimate your critical needs.

High Pressure Gas Quenching - Distortion Control

Not all high pressure gas quench systems are the same and pressure is only one part of the calculation in developing a gas quenching system.  To control distortion and minimize or eliminate post heat treat machining, your gas quench system must:

• Provide alternating (reversable) gas flow capability with flow equality in each direction.
• Provide homogenous gas flow, regardless of direction
• Vary wind speed
• Be capable of interrupting the quench sequence, holding a given temperature to enable the load temperature to equalize before continuing. 
• Use the most efficient gases
• Vary gas pressures
• Not be encumbered by non-quench specific equipment
