Useful video. I just heat treated some AEBL for the first time. All had been coated in condursal. 2 were completely coated and one I had left a section of the tang. The two that were fully coated stayed beautifully straight, but the one with some of the tang exposed warped along the tang. You might find coating the entire blade with anti scale helps with warping. Worth a go at least. Will definitely get myself some RWL34 to give it a go. Thanks for the information.
Definitely test your AEB-L for warps before HT I think you will be surprised,and a stress relief cycle at 670 for a hr as above in my reply to poltergeistworks.
I’m wondering if you tested the steel as far as bending it after heat treatment? I’ve found it to be a weird one because despite getting solid rockwell hardness I can straighten a warped blade on a press with not much effort. It bends pretty easily using a press even after heat treat without the need of over-bending which is really strange behaviour to me. I’ve always followed DAMASTEELs guidelines and asked about it but they didn’t say it was something abnormal :) For example in case of S35VN I have to significantly over-bend the blade on the press to get any bend into it/straighten it…
Hi buddy The test I done were snap tests to see what the grain structure was like,and edge retention tests after heat treatment. Since this video I now do an another cycle which is a stress relief cycle at 670c for 1hr after all drilling profiling and grinding has been complete. And it has improved the warping significantly with better results than in this video. I have also found on delivery of SF100,AEB-L,14C28N,80CRV have warps from manufacture,which are easy to remove before HT via a small Arbour press,so definitely worth checking your steel before HT I certainly was surprised. A bend test I would like to challenge myself ,like in the journeyman test.thanks for the comment take care Regards Davy
Isn’t it necessary to put RWL-34 in a wrapping foil because of oxydation? I would like to know this because i want to harden RWL-34 myself with my oven.
Yes you can buddy if you are plate quenching,I was oil quenching with ATP64 anti scaling compound. you can also treat it with Condurasal Z100 instead of foil buddy. Regards Davy
Hi Adrian I do have a plan to make a Bowie,but it’s a long way off yet.keep an eye out on my social media all of the same name and you can follow my journey. Davy
Nice simple instructions on how to use the evenheat kiln! Nice work Davy!
Thanks vince
Thanks for taking the time to explain so much. Love it.
No problem buddy

yes I have some condursal, but bought it after this HT. yes do try the RWL-34 its a real nice steel to work with.

well done davy, top video as always, and well explained, look forward to next video

Thanks Keith ,need to come see you soon,need some holes drilled on the flat pack grinder I showed you.
Thanks for the upload... doesn’t RWL34 air quench?
Yes you can plate quench and cryo ,but you can also oil quench with out cryo .

@@DTKcustomknives did you use any anti scaling compound? Or did you just let it be. Because you have almost no scaling.
Could you HT RWL-34 with no LN ?
Yes you can,however you can put it in your freezer for a couple of hours after quenching.
Davy
Long time...want one, a nice Bowie, not too long.
Hi Adrian

Will this steel quench in water?
Hi David
No buddy, I have followed the data from the manufacturer, get some quenching oil don't risk your hard work shattering.

Davy
