  • Hardness of Heat Treated 4140 Metal and Metallurgy

    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).

  • 4140 Alloy Steel Data Sheet

    4140 is an alloy steel that is supplied in either the annealed or prehardened condition. The prehardened condition is heat treated to a medium hardness (HRC 28/32) and is designated as 4140 HT. 4140 annealed is supplied in the soft condition and can be hardened to RC 54. 4140 annealed is designated as 4140 Ann or simply 4140.
