Can you heat to quench using a kiln?

[StrangeDaze]

I am looking at an evenheat kh 418.
Can you use it to quench a knife?

I think you have your terms mixed up.

That said, the oven (kiln) you're looking at will be sufficient to heat treat knives. Once you heat them in the oven, then you quench them in liquid, or let them air cool, depending on the steel type. You don't quench in a kiln.

An guy on Facebook the other day said his heat treater quenchs right in the kiln with liquid nitrogen. He said he just fills the kiln with liquid nitrogen. I want to see a video of that, I don't want to be anywhere around when he does it.

Sorry if i worded it confusingly(i've changed the title). I couldn't think of the term for heating before quench unless it is just "heating to quench" or something along those lines. What would the proper term be? And thank you for your answer!

In industry we'd call that "heat treat" which is overly generalized and only specific in context since "heat treat" could mean anything from hardening to tempering to thermal cycling or annealing. The technical term would be "austenitize." Only in knife making have I heard to the process of heating to hardening temperature and then cooling all together as "quench."

Forged in Fire in particular. "ermegerd there's only 10 minutes left he has to quench!"
