Quenching oils

LUBEX® QUENCH 10 MC

High-performance quenching oil with a high flash point and very low viscosity, formulated from specially selected base oils (MC - Molecular Conversion) and with a unique package of additives which provide more intensive quenching and after the cooling process, it leaves the surfaces of hardened materials smooth (if they were smooth before quenching) and without residues of deposits. It does not contain chlorine or PCB.

Typical use

It is used for finishing forgings and semi-finished products. It is also used in the processing of screws, springs and in many other areas. It is especially suitable for quenching components prone to damage. It is mainly used in open systems. Use in closed systems is also possible but with appropriate ratio of surface and weight.

High-performance quenching oil, formulated from specially selected base oils (MC - Molecular Conversion) and with a unique package of additives which provide more intensive quenching and after the cooling process, it leaves the surfaces of hardened materials smooth (if they were smooth before quenching) and without residues of deposits. It offers a suitable combination of viscosity and high evaporation resistance. It does not contain chlorine or PCB.

Typical use

Suitable for quenching with the highest demands on deformation and surface quality. It is used for quenching of parts with complex geometry, which are sensitive to deformations, e.g. quenching of bearings or gears of cars and trucks, machines, as well as thin punches with high demands on surface quality. It is particularly suitable for quenching in chamber furnaces, belt furnaces and is also suitable for continuous furnaces.
