#50 QUENCH OIL Low viscosity quench oil that approaches water in quench speed, yet gives a more uniform, less severe quench than water. Recommended for open quench system operating below 120 deg F.
AAA QUENCH OIL The most popular, widely used quench oil. This patented accelerated quench oil provides a maximum, uniform cooling rate for austenitized steels, as well as clean, easily washed work when properly maintained.
400 QUENCH OIL Similar to AAA but contains extra reservoir of accelerator additive for use in situations where excessive consumption occurs.
420 QUENCH OIL A "medium hot" oil recommended for accelerated quenching operations in atmosphere furnaces from 180 to 300 deg F. Produces uniformly well hardened parts while holding distortion to a minimum.
MARQUENCH OIL M An accelerated quench oil designed for applications at 250-350 deg F. The use of this "hot" oil is commonly encountered in carburizing and carbonitriding furnaces or where parts are prone to distortion and cracking.
THERMO-QUENCH OIL A "hot" or "marquenching" oil offering excellent thermal stability, high flash point and fast quenching rate.
VACUUM QUENCH OIL For use in quenching in integral vacuum furnaces. Offers excellent quenching rate and thermal stability, good viscosity, and low volatility.
HIGH SPEED VACUUM QUENCH OIL Faster quench speed than Vacuum Quench Oil above, but otherwise very similar.
QUENCH OIL ACCELERATOR Blend of mineral oils containing a high percentage of the additive used to provide the high cooling rates of AAA. Transforms most ordinary quenching oils into "accelerated" oils where faster quench rates are desired, or to maintain the AAA quench speed after prolonged use of the oil.
