I am running incoming inspection of stainless steel bolts, to be specific, A286. I am using hand-held XRF, so it is surface sensitive. All elements meet the requirement except titanium. Instead of 2% Ti, I am getting 1.5% consistently. I wonder if passivation/pickling process is known to suppress Ti concentration. Or any other reason why Ti is lower on the surface? Thank you.
