      Auto temper, I remove from the quench between 400 and 700 degrees and air cool after that. That's only on kitchen knives. Everything else is 2x 350 or 2x 400, two hour cycles. You should try a couple samples to see how tough it is at different quench temps

    80CrV2 is basically 1080 with 0.50% chromium and 0.20% vanadium. Or like O1 with the small amount of vanadium with less carbon and no tungsten. First off at 0.20% vanadium you will not get vanadium carbides, you'd have to have 0.50 or higher to do that. What does it do then? It restricts grain growth and is why I only buy O1 with the vanadium. O1 with vanadium can be held at austenizing temperature of 1475 for 15 minutes with no appreciable grain growth and you will squeeze the chromium and tungsten into making carbides as much as possible. Then a 450 temper for two hours two times for a hardness of 60.
    If I were forging I would use the 80CrV2 instead of 1080 only because of the vanadium helping to restrict grain growth, but the chromium doesn't hurt anything and does help in forging. Now if I were forging a knife and wanted the edge holding of vanadium carbides I would get CruForgeV steel, it has 0.75% vanadium with 1.05% carbon with 0.50% chromium. I have forged it and it is one hard edge holding steel and I tempered it back to RC 57, but vanadium carbides are harder than tungsten carbides and being less hard didn't affect trying to finish it nor its abrasion resistance.
    If you do not know where to find it Alphaknifesupply.com has it in 1/4" thick bars. It isn't very expensive, but my understanding is that Crucible who makes it has discontinued it, so what is out there is all there is going to be.

    Good video. I just started using 8670 and I love how tough it is. I haven't used 80crv2 yet but I know lots of people who swear by it. Like you said though 8670 is easy to get and inexpensive and for the minimal difference on edge retention I'll probably just run with 8670 till I start doing Damascus or San Mai. 8670 has nickel in it so it doesn't contrast well when forged into a billet.
