The only way I could post this is as text only, but here are the specs on Parks50
Parks 50 QUENCH OIL
CHARACTERISTICS:
50 QUENCH OIL produces high hardnesses in many types of steel ordinarily considered water
quenching. In the initial stages of the quench, 50 QUENCH OIL cools like water. As the cooling
nears the martensite formation range, this remarkable oil cools the steel slowly and uniformly to
preclude cracking or distortion.
The recommended operating temperature range is ambient to 120oF.
50 QUENCH OIL is as effective at 50oF as it is at 120oF because of its low viscosity. This is a big
advantage to many steel treaters who have oil quenching tanks without heaters. It also means lower
consumption because oil dragout is greatly reduced.
Most quenching oils flash at about 350oF; the flash point of 50 QUENCH OIL is 275oF. But, no
fire risk is present if ordinary precautions are observed.
No deviation from regular procedures are necessary to obtain the advantages of this superior and
unusual oil. 50 QUENCH OIL furnishes water quenched hardnesses with the lack of distortion
associated with oil quenching. It is safe to use as long as the temperature of the oil bath is not
allowed to become excessive. Even when cold, quenching rates are high and dragout is low.
FORM:
Typical Properties
Appearance: Light Amber Oil
Viscosity @ 100oF: > 5.8 cSt
Hot Wire @ 100oF: > 33.5 amps
Nickel Ball Time @ 100oF: 7 - 9 seconds
Flash Point: > 275oF
EQUIPMENT:
All equipment for 50 QUENCH OIL baths may be constructed of mild steel.
Electrical immersion heaters used to raise the temperature of the oil should not exceed 10.0 watts
per square inch, in a well agitated environment.
OPERATION:
Bath Parameters
Temperature: Ambient to 120oF
Velocity: > 100 FPM
Time: As required for appropriate metallurgical
transformation
CONTROL:
The quench speed of 50 QUENCH OIL should be monitored and maintained at > 30 amps at
100oF as measured using a HOT WIRE MACHINE (available from Heatbath/Park
Metallurgical). If quench speed becomes lower than 30 amps, a 5% addition of QUENCH OIL
ACCELERATOR will restore the speed and reinforce the anti oxidizing compounds in the
product. 50 QUENCH OIL may need centrifuging or filtering depending on sediment that is
dragged in. Sediment level should be maintained at < 0.5%. Absorption of furnace atmosphere
can cause the flash point of 50 QUENCH OIL to lower resulting in poor quench characteristics
and fire hazard. Should this occur de-gassing the oil at a temperature not to exceed 225oF will
remove the contamination. All efforts should be made to avoid water contamination of 50
QUENCH OIL. Water will cause very erratic quench characteristics as well as posing a serious
fire hazard.
SAFETY:
Precautions should be taken to prevent eye contact with product, minimize skin contact and
inhalation of vapor or mist.
As with any chemical, read the product labels health and protective measure information
statements before using. Consult the MSDS for full information on health effects and
protective measures. Utilize necessary protective equipment appropriate for the task at hand
and potential exposure to the product being used. Whenever in doubt, STOP and consult with
your supervisor before using/working with any chemical.
DISPOSAL:
Used quench oils should be removed by a qualified waste oil disposal service.
Under the Resource Conservation and Recovery Act (RCRA) regulations, it is the responsibility
of the product user to determine, at the time of disposal, whether a material should be classified
as a hazardous or non-hazardous waste.
NON-WARRANTY:
The data contained in this bulletin is believed by Heatbath/Park Metallurgical Corporation to be
accurate, true and complete. Recommended parameters are based on a typical process and may
be altered to accommodate specific requirements. Since, however, the final use of the product is
beyond our control, no warranty of results is expressed or should be implied.
