Heat Treatment
Quenching Oils are heat treatment oils blended from solvent refined base oil with specially selected additives that facilitate fast quenching through proper and controlled cooling, and have outstanding chemical and oxidation stability. Quenching Oils also have excellent thermal properties, low volatility, high flash, and fire points.
Quenching Oils serve two primary functions. There are different types of Quenching oils in India that facilitate the hardening of steel by controlling furnaces during quenching, and they enhance the wetting of steel during quenching to minimize the formation of undesirable thermal and transformational gradients which may lead to increased distortion and cracking.
→ Quenching speed adapted to your heat treatment cycles
→ Stability in service
→ Reduction in consumption by drag out
→ Resistance to oxidation and micro-organisms
→ Ease to clean
Modern heat-treatment processes are constantly making new demands on Quenching oils. Hardcastle Petrofer’s extensive development program ensures that our product range is more than capable of meeting new industry advances. We are constantly screening new materials for their suitability for our formulations and our existing product range is continually reviewed to ensure that the best available technology is used. Rich experience in understanding the application needs of Indian heat treaters has resulted in HIQUENCH series of quenchants to be the automatic choice of our Indian customers.

Heat Treatment Product Range
NORMAL SPEED OILS
for tool steels and general applications such as
semi-finished products and forged pieces, principally of alloy
steels.MEDIUM SPEED OILS
most preferred oil of heat treaters particularly for alloy, tool
and die-steel grades because of its
low viscosity and long tank life.MEDIUM FAST SPEED OILS
for alloy steels, fasteners, carburised parts with
good evaporation stability, suitable for use in
open and sealed quench furnaces.FAST SPEED OILS
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.ULTRA FAST SPEED OILS
for special steel grades and end use applications with
high evaporation stability.WATER WASHABLE QUENCHING OILS
containing advanced additive packages with water
wash-off characteristics.SPECIALTY QUENCHING OILS
customised to suit specific
performance parameters.
-
MARQUENCHING OILS

SPECIALTY OILS
to suit customized performance needs of sophisticated applications.
POLYMER QUENCHANTS
POLYMER QUENCHANTS 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.INVERSE SOLUBILITY TYPE POLYMER QUENCHANTS
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.UP-CONCENTRATION TYPE POLYMER QUENCHANTS
Used for a variety of applications ranging from quenching of open
die-forged components like turbine shafts, seamless rolled rings,
valve bodies, bars, die steels, tool steels and coils of
martensitic stainless steel.
CARBURISING FLUIDS
Free of hazardous chemicals having a long established
high performance quality for achieving best
carburising results.CARBURISING (CYANIDE) SALTS
for high stability and consistent results.
CARBURISING (NON-CYANIDE) SALTS
for start-up under neutral condition, thus providing scope for
addition of Cyanide to suit the concentration requirement.
NEUTRAL HARDENING SALTS
for pre-heating, austenising, quenching of high speed steels and marquenching.
AUSTEMPERING SALTS
for tempering and drawing of variety of steels including spring steels.
WATER ADDITIVE SALTS
