Best quench oil for O1?

[Everglade Blade]

I'm looking for the best/right oil for quenching O1 steel. Any help would be great.

I used canola oil and it worked well, but there's probably something better.

01 takes a medium speed oil whichever one you use.

As Fred Rowe said, a medium speed oil. Canola may be a tad fast, but other vege oils such as peanut, may do well enough. If you want the best, and oils with a longer life span than grocery store oils, go with a commercial quench oil. Parks AAA is very popular for 01, and is what I use, but there are others just as good.

The big home center stores usually carry 3 Gal. jugs of deep fry oil which is mostly peanut oil. This works fine for 01 if you want a readily accessible source. Otherwise a commercial quenchant like Parks AAA should do well.

Thanks, I'm gonna go with parks, I've been using canola. I want to try something different, and see what results I get.
