Pennine Quenching Oils are developed for the conventional and accelerated heat treatment of
carbon alloy steels. Manufactured from low viscosity solvent refined mineral oil, they have excellent
resistance to oxidation and good water shedding properties.
Applications
"22" and "32" grades are recommended for conventional oil quenching where the majority of
hardening operations will be satisfied.
“22 AC/M” and “32 AC/M” are partially accelerated quenching oils offering a moderately improved
cooling curve together with the benefits of excellent oxidation stability and lower internal stresses
than the “AC” grades. These products are recommended for applications where a wide variety of
steels are to be heat treated and a degree of rationalisation is required.
"22AC" and "32AC" grades are high performance quench oils providing accurate degrees of
hardness with minimum deformation whilst ensuring that components are free from surface
staining. They endure the most severe operating conditions and offer excellent oxidation resistance,
maintaining a stable performance throughout their long service life.
