Park's 50 Quench Oil - 1 Gallon Jug
Brand: USA Knifemaker
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 120°F. 50 QUENCH OIL is as effective at 50°F as it is at 120°F 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 350°F. The flash point of 50 QUENCH OIL is 275°F. 50 QUENCH OIL furnishes water quenched hardness 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 exceed 120°F and vigorous agitation is used. Even when cold, quenching rates are high and dragout is low.
Typical steels to use with this quench oil formula include: W1, W2, 1095. Many other steels using “fast” speed (there is no hard and fast definition of “fast” or “medium”) will be appropriate with this quench oil.
Appearance: Light Amber Oil, Viscosity @ 100°F: > 5.8 cSt
Nickel Ball Time @ 100°F: 7 - 9 seconds, Flash Point: > 275°F
Parks 50 is considered a fast oil. Many times a quench oil is described in seconds quenching using a Nickel Ball test. The Nickel Ball quench time is 7-9 seconds.
