Normal PMI equipment like XRF spectrometer cannot identify C. From my knowledge , it must be portable spectrometer or similar which will be more expensive than normal PMI. If PMI is required for stainless of which carbon content is the issue such as 347H , it is possible that the client will require PMI result with carbon content.

Dear friend,
This material is something like CK30. But this kind of material is heat treatable and you have to sure about this. It is recommended to have a metallographic test on it for undrestanding such a heat treatment.

Dear Experts,
We did PMI test on one unknown machine bolt from crane boom rest and result is as follow:
Can someone tell me how can we trace the steel grade base on this result.
Is there any software available?
Thanks and Rgds,
