i've been reading in the history section that the quenching oil [i use canola oil ] should be at 140-160 degrees. what is the advantage of having the oil warm. thanks as always jackie
-
Warm oil cools faster than cool oil.
And 1095 needs to get from around 1500 to below about 950 in 1-2 seconds.
But it's such an ambiguous and relative activity.
A lot depends on the condition of your steel and how you have austenized it.
As well, the thickness plays a part.
Commercial quenchants like Parks #50 only need to be room temp where it was designed to extract at the heat of water/brine.
Lot of things involved here.
Do you have enough fluid/volume where you can move the blade around once you have quenched it?

yes most of my blades are 3-4 inches long and i use a 2 pound coffee can full of canola oil.
