High Performance, Highly Accelerated Cold Quenching Oil




Houghto-Quench 3440 is an accelerated quenching oil suitable for use at temperatures up to 180°F (82°C). It is based upon specialty solvent refined base oil to minimize oxidation and ensure consistent performance under the most arduous of operating conditions. A carefully formulated additive package is incorporated into Houghto-Quench 3440 to reduce the duration of the vapor blanket cooling stage and provide accelerated quenching characteristics, together with excellent oxidation resistance and thermal stability.




The highly accelerated speed provided by Houghto-Quench 3440 enables the development of optimum strength and hardness with minimum distortion in lower hardenability and low alloy steels, heavy sectioned components or steels of borderline hardenability.


Houghto-Quench 3440 is suitable for use in all types of quenching installations including open quench tanks, sealed quench furnaces and continuous furnaces of the shaker hearth, cast link and mesh belt type. It is recommended particularly for applications where staining of components during quenching should be minimized.

·         Fast cooling rate in initial stage of quenching: Maximum metallurgical and physical properties

·         Minimal drag-out of quenching oil: Less smoke and makeup required

·         Excellent oxidation resistance and thermal stability: elimination for waste due to quench oil degradation
