But an etchant would bring out the quench. And you would see a difference between the quenched zone and the "unquenched" one

An xray might be interesting to see. Know anyone who works in a hospital or Dentist's office?

Hello Rick,

An xray might be interesting to see. Know anyone who works in a hospital or Dentist's office?

From the pamor extending across the line, it seems safe to assume that we don't see any differences on a macroscopical level here. Thus, I don't think x-ray will be of any help here.

Yes, any difference in final composition (steel alloy, heat treatments, etc.) will show up by etching/staining.
