4140 steel hardening

  • How to Harden 4140 Steel eHow

    However, different steels have different hardening steps to follow. Some of the most difficult steels to harden are tool steels. ANSI 4140 is a tool steel with relatively high amounts of elemental additives. It requires specific steps to produce a hard edge.Read More

  • Heat Treating & Hardening 4140 Steel Material

    Jun 30, 2006 · 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 the core to be softer you can first normalize, or quench & temper in a furnace to the desired lower hardness level. This treatment also prepares the near surface for optimum induction hardening response.Read More

If you want theSo 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 indThanks for the replies, Using 8620 steel will require extra machining and grinding due to the extreme warping in the metal. Nitriding the part willmetal for metal, 8620 will exhibit a better resistance to impact load due to the present of nickel element. A good design must have a balance amongyou could also use 1045 (which would probably be cheaper due to the lower alloy content) and heat treat it. It WILL case harden but it will not thr1
