or tool steels and general applications such as semi-finished products and forged pieces, principally of alloy steels.

most preferred oil of heat treaters particularly for alloy, tool and die-steel grades because of its low viscosity and long tank life.

Used for a wide range of applications ranging from quenching of forgings of low-alloy and plain carbon steels for automobiles such as crankshafts, connecting rods, camshafts etc., steel castings, bars and sections of low-alloy carbon steels, hardening of hand tools, spanners, wrenches, tongs, high-pressure cylinders, .

for lean alloy steels, heavy section parts, plain carbon steel, bearing steels and carburising grades of steels, having high evaporation stability and rapid breakdown of vapour blanket for high cooling capacity. 

for high-performance hot quenching with excellent ageing stability for a wide range of applications requiring good hardening efficiency, distortion control and long service life for small as well as large size components. These oils are suitable for use in sealed quench furnaces as well as open tank quenching applications.

PQP HD developed with specially selected polymers so as to ensure long and trouble-free service life. Preferred for use in induction/flame hardening and tank quenching applications for various grades of steel, castings as well as for solution treatment of distortion prone aluminium sheet for aerospace and components of automotive applications. 
Used for a wide range of applications ranging from quenching of forgings of low-alloy and plain carbon steels for automobiles such as crankshafts, connecting rods, camshafts etc., steel castings, bars and sections of low-alloy carbon steels, hardening of hand tools, spanners, wrenches, tongs, high-pressure cylinders, seamless tubes and carburised or carbo-nitrided small parts.
