Castrol Iloquench 1

VISCOSITY - ISO 20

General Purpose Cold Quenching Oil

DESCRIPTION

Castrol Iloquench™ 1 is a general purpose, low viscosity quenching oil. It is based on selected solvent refined mineral
oil highly resistant to oxidation and therefore offers long service life with minimum deterioration of properties during
service.

APPLICATIONS

Iloquench 1 is a universal quenching oil for use in cold quenching applications of medium to high carbon as well as low
alloy steels to impart the desired hardness to the components without metallurgical distortion or stress.
Iloquench 1 is suitable for use in continuous furnaces, sealed quench furnaces and open quench tanks. It may also be
employed for quenching parts heated in cyanide salt baths. Due to the low sulphur content Iloquench 1 is not affected
adversely by the carry-over of cyanide salts.
Iloquench 1 is particularly suitable for the quenching of small components because its low viscosity enables the
surfaces of small, intricate profiles to be wetted effectively, enabling the most efficient heat transfer. Its low viscosity also
reduces drag out losses to a minimum. Typical treated parts used to be nuts, bolts, ball bearings, hand tools and
springs.

ADVANTAGES
  • Inherently resistant to oxidation and thermal degradation leading to a longer service life.
  • Consistent quenching performance and metallurgical standards of output.
  • Provides clean surfaces, free of stains, patches, spots and marbling aspects.
  • Low viscosity ensures minimum drag out losses helps to ensure the most effective heat transfer.
  • Versatile – compatible with all methods of component heating, including salt bath heating.
  • Easy to clean-off by using alkaline process cleaner, also available from Castrol.
