I usually temper O1 at 400F. I temper right after quenching. I temper twice an hour each time.

Thank you. it complies with the previous post.
Very interested in holding time during hardening
Do any of you pros test RC? is there a non destructive of doing so? today
No I don't test, for the simple reason of not having a hardness tester.
Hardness testing (Rockwell C) is non destructive.
I sparktest the blade and the edge in particular.
If I get a nice shower of sparks, I know the heat treatment was successful.
I choose the tempering temp to end up with an expected hardness. It may differ by a point, but when all is said and done: it doesn't matter that much whether the hardness is 61 or 62.
I only test the HRC when I get a new batch of steel, doesn't matter if it's coming from the same company. They sell hardness testing files that range from Hrc 40 through 65. They come in a set of 6 and increment by 5 HRC. That can give you a basic direction. There's are also standing or portable handlheld models that are more precise but cost much more and need to be calibrated every so often.
