Why do PMI test for stainless steel?

- Jul 18, 2018 -

Sometimes a positive material identification (PMI) is required for safety critical items such as LPG valves - this is an individual confirmatory analysis on each finished item.

Some products may be lacking in documentation and traceability; the most common concern is stock mixed in storage or as incoming scrap.

Unexpected poor performance often prompts calls for material testing. Such testing removes one variable in things that might have gone wrong but the cause is more frequently inadequate surface finish or errors in design or fabrication.

Finally, reverse engineering of an existing product often requires detailed materials information - generally more than just composition.

So skyray instrument can offer different products such as OES spectrometer, XRF spectrometer including handheld XRF alloy analyzer for the stainless steel analysis.
