Incorrect......."the depth of hardening is ultimately limited by the inability of carbon to diffuse deeply into solid steel".....check with any metal laboratory or metallurgist.....

That is why for over 150 years it was called the "hardened skin"......

Yes, I agree with your comments and observations.....I still block most parts, but do not use stainless....but low carbon steel blocking.....and as you stated......as long as CCH is done properly....i.e. temps etc......I totally agree.....

Best,
