1095 quenching oil temperature

[jackie]

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.
