Hi all,
I am looking to try some stainless kitchen/chef's knives in AEB-L.
My intent is primarily slicer, relatively higher hardness, fine edge,.
I have read a fair bit, such as listed in below links...
It seems, although I am a bit slow, that I should be able to get a "reasonable" result from dry ice + liquid medium (denatured alcohol, kerosene, mineral spirits, etc)
meaning potentially a 60-ish+ Rc with decent enough Martensite conversion ?
(assuming all goes well, well controlled, ....)
I don't make enough knives probably to warrant a liquid nitrogen cryo setup. I am not opposed to it, but it is a lot of $$$ it seems.
That being said, if it is worth it, I will pay it
If you have any suggestions as far as will I regret going with a DIY dry ice+ vs. LN please advise ?
In other words, am I kidding myself, and is dry ice+medium a waste of time?
Here are things I have read/researched which seem to indicate that LN is better obviously, but that dry ice+liquid medium in between LN/freezer, and could produce results in the range I am looking for ????
Apologies ahead of time for my ignorance, I am learning.

"Cryo is not an on/off thing, and the colder you go the better for minimizing retained austenite. I found this with my own experiments of AEB-L as in the previous plot. Below shows martensite content for T1 high speed steel at different temperatures:"

While liquid nitrogen is preferred, a sub zero bath with dry ice and kerosene will suffice for -100°F /
-74°C.
Submerge in sub-zero treatment 30 minutes to 1 hour depending on thickness and number of blades.

Dry ice + denatured alcohol? mineral spirits ?
Ken, not trying to be a smart ass here, but why do you feel the need to add acetone to the dry ice for sub-zero quench? Everyone does it, but there's no reason the dry ice has to be a liquid, and it adds cost to the process.. Potentially longevity to the dry ice is diminished also, but I'm guessing here.

AEB-L Heat Treat Problem?
Hey guys, I was "attempting" to heat treat a few AEB-L knives today. Followed the standard recipe I found on a few sites. 1. Preheat to 1560F and equalize. 2. Ramp to 1940F. Then increased to 1975F and held it there for 15 min. 3. Quenched in canola oil a little over 100F. This was done...
