Quenching oil is used for all normal quenching operation on a wide variety of steel to impart the desired hardness to components without distortion. Some special compound incorporated in improves the wetting ability of the quenching oil, so that it provides faster initial cooling for initial cooling for optimum hardness, where as the base oil ensures slow cooling in the final stage for stress relief and distortion free results. This petroleum product is normally applied for hardening nuts, bolts, ball bearings and certain type of brake drum as well as many other components manufactured by automobile and light engineering industries. This oil petroleum is suitable for hardening of a variety of ball bearings, high-speed steel tools and other components in major industries. This engine oil has long service life due to excellent, oxidation stability, impart uniform hardness without distortion and has outstanding thermal and oxidation stability in service at elevated bath temperatures.
