Front Combo Stubs

[atomicjoe23]

Was considering either Induction harden or Thru Harden.

What do you think?

I'm assuming you mean surface induction hardening since you can through induction harden as well. . .I have no induction hardening experience, I only have experience through hardening and case-hardening with an electric heat treat oven, propane forge, and coal forge. Case hardening is a surface hardening heat treatment, but in the applications I have used it the depth of heat treat was not very critical. . .

. . .in this situation the depth of hardening would be important, too shallow and there is the potential to remove the hardened zone when the part is ground (assuming it will be ground after heat treat & quench) too deep and you may defeat the purpose of only surface hardening the part.

So the question is, do you know how deep you should harden the material if you surface induction harden the part? or does the heat treater's facility you are going to use have experience with these types of parts and can help you choose the correct depth of hardening? If the answer to either of these questions is no, then you should probably just stick with through hardening.

Hi guys thanks for the replys, I'm machining the front stub and the lower part of the upright from one piece, so was wondering what would be the best option regarding heat treatment and material.

I think this is what you should be doing. . .

4130/4340 H.T. to 38/42 Rc would be my
reccomendation.

through hardened.
