    Jun 30, 2006 · Heat-Treating & Hardening 4140 Steel. If you want the part carburized to your spec, then the suggestion of 8620 by arunmrao is a good one. If you want the part induction hardened and tempered to your spec, then 4140 would be ok. I would limit the hardness to be under 60 HRC if it is 4140, but 55-62 HRC is fine for carburized 8620.4140 is not case hardened by carburizing but it is frequently induction hardened to the hardness and depth you desire and beyond. If you want thebest 4140 steel heat treatmentSo what youre telling me is that I can have my components Heat-Treated & Hardened to my specs? Any response will be greatly appreciated!If you need surface hardness and the core to be tough,you can consider 8620 instead of 4140 alloy.TorsionalStress, It is not quite as simple as yes or no. Case hardening is typically used to mean carburizing, but it is also used to describe indbest 4140 steel heat treatmentThanks for the replies, Using 8620 steel will require extra machining and grinding due to the extreme warping in the metal.
