Heat Treatment Protection Compounds (Stop Off Paints)

Petrofer manufacture every type of quenching oil, from simple heat treatment oils for hardening high alloyed steels all the way through to accelerated quenching oils for achieving maximum hardness depth in low alloyed or plain carbon steels.

We also have water washable versions of almost all of our heat treatment oils available as well as specialist synthetic (mineral oil free) biodegradable quenching and tempering fluids.

All of our quenchants share a common trait, they are manufactured with the best quality additives to ensure low oxidization, (best resistance to ageing) and minimal evaporation.

ISODUR RANGE

Normal speed quenching oils for hardening high alloyed steels.

ISOMAX RANGE

High-speed, low-viscosity quenching oils normally used in open quench tanks for hardening of fasteners, springs, die-forged parts, bar and sections.

ISORAPID RANGE

This product range has been specifically designed for sealed integral quench furnaces and is particularly useful for quenching from continuous belt furnaces.

MARQUENCH RANGE

Hot quenching oils with outstanding oxidation resistance. Used widely for hardening of automotive transmission components, large gears and many other parts which are susceptible to distortion.

VACUQUENCH RANGE

Our vacuum quench oils have been developed in collaboration with manufacturers of vacuum furnace equipment to ensure that they deliver suitable vacuum conditions and spotlessly clean parts. All of our vacuum quench oils exhibit an extremely high degree of purity, have low gas absorption capacity and rapid degassing capability.
