It is well known that distortion has and continues to present a challenge to the heat treater when hardening/carburizing gears.  However, recent advances in quenching technology are improving the opportunity for improved distortion control. 4 Dimension High-Pressure Gas Quenching (4DQ) is a unique gas quenching process that uses both a special quenching chamber design with part rotation to minimize distortion during the quenching process.  4DQ gives one the ability to “engineer” the quenching process by controlling quench pressure, gas velocity, gas manifold design, table rotation, table oscillation, and time-dependent gas flow. The system’s flexibility allows users to customize the quenching process for reduced distortion, providing repeatability and precise accuracy in their heat treatment.
