Joshua States Posted September 12, 2021 Share Posted September 12, 2021 (edited) There seems to be a "conventional wisdom" out there that quench oils need to be preheated before the quench. I'm not talking about canola or peanut oils, but about industry quenching oils. I am a big fan of following manufacturer's reccomendations when using their products. So I went to Dubois Heatbath and found the spec sheet on some of the more commonly used oils here in the States. There are specific temp ranges for these oils. So remember, if you are quenching multiple blades, the oil will heat up after each quench. Now, my quench tank holds 5 gallos of oil, so I don't worry about that particular effect, but if your quench tank is significantly smaller, you might want to consider it.

I've been there before.” The only bad experience is the one from which you learn nothing.
