ive also seen a lot of alloy segregation in 17-4 in the wet bench that looks like cracks on the surface of thicker materials, and centerline lamination in thinner plate (viewed at the plate edge) metallurgical examination can prove the presence of alloy segregation but is a flawed method for accepting lots, I believe eddy current can verify continuity without destructively testing parts, and do it on every indication instead of a cross section of 1 in a lot.
Hello, I need to know what is the maximum examination thickness in pieces to be inspected in a wet horizontal unit for MT magnetic particle tests or through the use of the magnetic yoke, either by wet or dry technique. I have reviewed the ASNT NDT Handbook Vol 8 MT and the ASTM E 1444 and E709 standards and I have not found information about it. I would greatly appreciate your response.
They won't endorse any claim on a depth. It is surface "and slightly sub-surface" only. I can tell you that I have seen subsurface shrinkage in castings with an AC yoke. It was extremely severe though, so... there's that..

I would love if magnaflux sold filters for 14A powder that fit standard automotive style parts washers

New Zealand. Picked up a Magnaflux machine. Now need to figure out how it all works
