INDUCTION HARDEN ASTM A514
INDUCTION HARDEN ASTM A514
(OP)
Attempting to replace a European mtrl specification with something commercially available in the USA. ASTM A514 has been suggested due to the fact that the required mechanical properties of ASTM A514 are within spec.
However, the original design required some sections to be induction hardened. Spec is HRC 50 0.3 mm deep, I know HRC is probably not applicable but this is the original spec on the drawing.
Can ASTM A514 safely and successfully induction hardened (without detriment to the core properties)?
It was my understanding that in general carbon content should be between 0.3-0.4% for induction hardening.
Thanks!

RE: INDUCTION HARDEN ASTM A514
You will not achieve 50 HRc on the surface because the carbon content is too low. The A 514 steel plate grades typically contain carbon contents from 0.21 down to 0.15%.

RE: INDUCTION HARDEN ASTM A514
Parts are stamped and formed (nothing extreme) prior to hardening so distortion due to hardening process is likely to be a problem.
It is possible that the hardness of the A514 is already sufficient. We are unfortunately trying to revive a very old design so we can only hope to replicate the obscure material specified, no time to fully redesign the part.
