    I can get my hands a bit of Fenso 150, how would this be different then the heated canola that I now use? I make mostly simple steel blades, O1 and 1095. Is this a move in the right direction or just a direction change?

    I could look it up, but for the basis of having a conversation here, what speed rating is Fenso 150?

    Looks like a 9 second oil

    for 1095 you would want at least the 90 version which is a 8.6 second oil and that is close to the Parks 50 7-9 second rating

    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 Properties

    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.

    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.

    Caution: All quench oils are flammable. Be prepared to smother a fire in your quench oil container should your oil reach Flash Point. Never quench using a plastic container to hold your quench oil! Hot metal can melt a hole in plastic and the oil leak from the hole can spread flaming oil around your shop! Keep a fire extinguisher close by.

    We suggest checking the temperature of your oil as you use it. Over heated quench oil reduces the life cycle of the product. Many smiths do not pre-heat Parks 50 to 120°F as other quench oils recommend.
