Cru Forge V Quench result

[Karl B. Andersen]

Karl, I feel you will get a tougher blade, quenching Cru V in a slower oil.

Although it should work fine, I'd save the Park's 50 for W2, W1, 1095 etc.

Good advice, and well taken.
Thanks, Dan and Don.

Don and Dan, If CruforgeV is deep-hardening, then why did Karl get apparently different zones of hardening on his blade when he quenched it in the Parks 50?
Usually you don't see that sort of thing occurring on a deep hardening steel, right?
- Thanks

I see it all the time with 52100, which is a deep hardening steel

What Bill said. Also Karl's blade might not have reached critcal temp in the spine?

Need more info from Karl to figure out what's gone on.

Thanks, guys. I'm trying to figure out what's going on with this new steel.

I would say Don may be fairly correct.
The combination of the clay and the austenizing created a pretty neat effect.
I had my forge turned down pretty good so as not to overheat anything. Really watched my heat in the blade - kept the thinner areas at heat be pulling out of the forge and placing back in.
Don will see it next weekend.
