CASTROL ILOQUENCH 700 AQUA

Castrol Iloquench 700 Aqua is a high-performance quenching fluid that is designed to meet the rigorous demands of steel production. Thanks to precision engineering, Iloquench 700 Aqua is proven to reduce the occurrence of cracking or warping in induction or flame-hardened steel and cast iron components.


Castrol Iloquench 700 Aqua is versatile enough for use in treating a variety of components, from gears and axles to saw blades, and provides a variable quench rate that can be controlled by adjusting the concentration but which generally sits at the midpoint between water and oil.


The product is a polymer quenchant that is designed to deliver superior cooling performance, providing a high cooling rate in the initial stage of quenching, followed by a slower cooling rate in the intermediate and final stages. This controlled cooling process helps to minimise distortion and cracking, ensuring a high-quality finish.

CASTROL ILOQUENCH 700 AQUA

Castrol Iloquench 700 Aqua is a high-performance quenching oil that offers superior cooling performance, extended service life, and enhanced safety. As part of Castrol's broad metalworking fluid range, it is renowned for its superior quality and performance. For optimal performance, consider using the Iloquench 700 Aqua in conjunction with other products from our range, including Castrol’s Rustilo Aqua water-soluble corrosion inhibitors, which are compatible with Iloquench 700 Aqua and suitable for use in a wide range of applications.


Concentration can be changed to vary quench rate and suit a range of applications. This means Iloquench 700 Aqua is ideal for quenching everything from carbon steel to high-alloy steel products. In fact, this oil is often used to treat the following components during the manufacturing process:

  • Crankshafts
  • Transmission shafts
  • Saw blades
  • Axles
  • Gears
  • Push rods
  • Rocker arms
  • Rolling mill cylinders

The oil has a high flash point, which enhances safety by reducing the risk of fire. It is formulated with advanced additives that enhance its oxidation stability and thermal stability. This helps to extend the service life of the oil, reducing the frequency of oil changes and lowering maintenance costs.

Buying quenching fluid

Choosing the right quenching fluid is a vital way to maximise the quality of your finished products, and can help to avoid faults, warps, cracks and other serious problems. However, it is not always easy to understand what the differences will be between products, or the results you can expect.
