My HT oven's parts are trickling in slowly, and I think I should buy some quenching oil. I am going to be using 1080 and 1084 steel to practice heat treating. From my understanding these are fast quenching steels. I am assuming that the 11 second quenching oil from Mcmaster will work for these types of steels. Is this correct? Once I get the hang of this I will buy some higher grade oil and explore different steels as well. For now in-expensive is whats on the menu. Thanks again gentlemen.
 
I believe it will do just fine. I'm under the impression that Cashen has looked at metallography and otherwise evaluated it, perhaps he will chime in here.

I use it for non-knife related stuff, though I have quenched a file knife in it (similar to 1095) and got what appeared to me to be excellent results.
 
I use the M/C 11 second oil on my 1084, and damascus made with 1084/15n20.I get very good results with it.

Thanks for the input guys, I just ordered me a couple of gallons to start off with.
 
Are you guys preheating your McMaster quench oil?
If so, what temps?

There's very little info on the 5 gallon pail.
 
Be aware that moderate preheating will probably get you under the nose faster, but it can also increase total time to Ms, so an 8 second quench to pull out and straighten might turn into a 12 second quench.

Personally I like it hot enough that you can still hold your finger in it, about 120. When you pull your work out, it should steam, but stay wet. This is the best time to iron out any little kinks. (Thank you KC)
 
I use this oil for 1084 & 1095. Will this oil work for O1? Been wanting to try some but don't want to buy another oil.
 
I use Brownells Tough Quench, and I think it is a 10 or 11 sec. oil, on O1, works great as O1 requires a medium speed oil. So the M/C oil should be fine for O1.

So does anybody use this with 1080 steel. I would imagine it to be similar in results to 1084.
