2x Chromium in A532 using PMI
2x Chromium in A532 using PMI
(OP)
Why do I obtain readings from a calibrated portable alloy analyzer (Xray tube) of 45-58% Cr for A532 (28G) material which should be 23-30% Cr? Is it due to the volume of carbides on the surface of the cast impeller part between the interdedritic structure? I have no way of verify the microstructure currently so I'm taking a stab at it. Could someone please let me know if my thoughts are correct?
Thank you,

I think you hit the nail on the head. I ASSUMED the surface of this material was prepared as it is in an abrasive slurry bath, and was visually a white metal finish, however, I should have taken some sandpaper in with me during this inspection.
Won't make the mistake again!
