The maximum hardness that can be obtained in any steel depends on carbon content. The section size in which maximum hardness can be obtained depends on alloy content. 4140 has a nominal carbon content of .4% and this carbon content will yield a hardness of Rc 51 for a 90% martensitic structure (9th Edition of the ASM Material Handbook,Volume I).

May 31, 2009 · If I didn't have any 4140 I'd use 1045. If I had to buy some steel I'd buy 4140. the 4140 specs don't show it, but the proper welding rod for it is also 7018. which makes it easy for building tooling. Weld then heat treat. IF I was making an anvil I'd defianantly use 4140 for the top plate. it would be way tougher than the 1045.
