Can I mix olive oil and vegetable oil for quenching?

[Shovel]

So, I don't have enough oil to quench my knife in just one of the oils, so can I mix them? I'm HT'ing 01 by the way.

 

[nic.]

Yes - some cheaper olive oils are blended with vegetable oils anyway from what I can gather.

Does it give a different quench from old engine oil? Other than the smell of course?

I'd be interested to see scientific results.

I thought it was best to quench in a mineral ie engine oil? Vegatable ones have a much lower burning point I believe, sure someone more knowledgable will be along soon to give us the full facts and figures

Some steels are water hardenable, some better in brine and some in oil.
The W in W1 (File steel) refers to Water.
The O on O1 refers to Oil
The A in A2 stands for Air.

There's a lot more to it than that and I've only really looked at it with regards to weld inspection so I'm sure someone with a brain will be along shortly.

Well, actually have no idea. Again some with a brain will be along shortly. With luck.

I use veg oil to quench O1, its really forgiving. Go for it I'd say...smells like fresh chips

Everything you ever wanted to know about steels and probably a lot you don't Have a look about halfway down the page.
