It is also very expensive steel compared to some of the higher carbon simple steels like 1080/84 and 1095.
It's great stuff to have around for making tools, punches etc but not the best for knives.

4140 is deep hardening, isn't it? If so, why?
Hey Tyler, not that I've forged 4140, but I see in the books that 4xxx is molly-whatever, and mollybidium is supposed to impart a deep hardening characteristic to the steel. My books are home and I don't remeber what the 1 is, as in 41xx, but the 40 is .40% carbon (less that half as much as 1095).
I don't know if this is really what you meant by your question, but if it is, you ought to go to the library and get a hold of Dr. Jim's book or one of the other knife books. The description of the codes and the characteristics of the steel is real interesting.
