I don't work with S30V or 440C so I was a little hesitant about answering your post. The best advice that I can give is to go to Alpha Knife Supply and look under their knife steel selections. You can find heat treating information listed there, however, my gut feeling is that S30V does not heat treat like 440C. Without looking up the information I would expect to see that there are more high temperature carbides in S30V that will require a higher and longer temperature soak to put carbon into solution.
