Ran across this interesting table and graph, thought I would share. The source cited (4) is Siebert, Doane & Breen, The Hardenability of Steels, ASM, 1977. Moral to the story: Not only does an increase in carbon increase the ability of martensite to form, but it also corresponds to an increase in hardness for the martensite as well. I don't have the source material at hand, but I think it is safe to assume that "excessive" alloying elements besides Fe and C will also change the overall hardness. The paper I was reading that this chart appeared in did not go into any specifics in this case either.
