CASTROL Iloquench 768 Aqua FF
Quenching Oils
Water soluble polymer quenchant for quenching of steel components in induction or flame hardening applications to reduce the occurrence of warping of cracks. Typical components treated are crankshafts, gear, axles, transmission shafts, saw blades, rolling mill cylinders, rocker arms and push rods.
This fluid minimises the creation of a stable insulating water vapor layer (Leidenfrost phenomenon) and hence reduces the risk of soft spots and cracks. In general, water-based heat treatment fluids provide a safer working environment by reducing the fire hazard risk.
Iloquench 768 Aqua FF provides a quenching rate which is intermediate between water and oil and which can be varied by altering the concentration. The quenching result is affected by many parameters, such as the metal alloy, the geometry of the part, and the required depth of effective quenching and the method of application. It is recommended to perform preliminary tests on the unit under consideration for optimising the process parameters.
Iloquench 768 Aqua FF contains corrosion inhibitors and antifoam agents, but it is formulated without formaldehyde releasing biocides.
Recommended conditions of use:
Temperature of bath: 20 - 45 °C
Concentration for carbon steel and low-alloy steel: 5 - 15 %
Concentration for high-alloy steel: 15 - 25 %
Concentration for austenitic steel metals, pipes, profiles: 5 - 10 %
Refractometer factor: 1.83
Note:
Since significant contamination can substantially affect the quenching performance it is strongly recommended to minimise the drag-in of soils, such as quenching salts, coolants, corrosion preventive agents and hydraulic oils (particularly HLP-D) as best as possible.
