How do I select the best quench oil for heat-treating?
The selection of the proper quench oil is critical for proper heat-treating operations. The quenchant selected must provide consistent quenching the first time, as well as over the life of the quenchant. Improper selection of quench oil can result in short oil life, or soft parts. Improper maintenance of the quench oil can result in stained parts.
What makes for successful heat treating?
Successful heat treating begins by understanding the make-up of the steel that is to be treated. The American Iron and Steel Institute (A.I.S.I.) and the Society of Automotive Engineers (S.A.E.) utilize a four-digit system to code various types of steel used in manufacturing.

Water is one of the most efficient quenching media where maximum hardness is desired, but there is a small chance that it may cause distortion and tiny cracking. When hardness can be sacrificed, mineral oils are often used.
What oil Can you use to harden steel?
Mineral Oil OilMineral Oil Oil is a third traditional quenching agent, suitable for high-speed steels and oil-hardened steels, and in fact for any steel for which the required degree of hardness is achievable. Oil has a slower rate of cooling compared to either water or brine, but faster than air, making it an intermediate quench.
What oil do you use to quench a knife?
canola oilMany knifemakers recommend using canola oil heated to around 130℉, saying that water tends to cool the steel too quickly, which can lead to cracking, especially if the blade is on the thin side. In comparison, oil has a slower cooling rate.

Is water or oil better for quenching?
Water-quenched steels will generally be harder than oil-quenched steels. This is mainly because the thermal conductivity of water is higher than the thermal conductivity of most oils (that I know); consequently, the rates of cooling will be less rapid (or lower) in oils compared with water.

Quench oil serves two primary functions. It facilitates hardening of steel by controlling heat transfer during quenching, and it enhances wetting of steel during quenching to minimize the formation of undesirable thermal and transformational gradients which may lead to increased distortion and cracking.
What type of oil is used to harden ferrous alloys?

What is the selection of quench oil?
The selection of quench oil is dependent on the part, type of furnace, and cost. The part requirements are critical. The alloy must be considered to achieve the proper hardness and required mechanical properties. Geometry and section size are influenced by the hardenability of the alloy.
Why should fast oil be chosen?
The oil must be chosen, as well as the method of fixturing, to minimize the potential of distortion and quench cracking. The furnace also influences the choice of quenchant. If the agitation in the quench tank is poor, then fast oil must be chosen.
Does oil drag out more?
Consumption of the oil by drag-out should also be considered in the quench-oil calculations. Higher viscosity oil will tend to drag out more, as will high surface area parts. The method of racking parts can cause the retention of higher-than-normal quantities of oil.
