Positive Material Identification (PMI)

[ritsa p]

We performed PMI testing on surface of some unknown base metals.
The results of chemical composition are mentiοned below:
1. Fe A-9 [-230.4]
2. Fe S-7 [-74.4]
3. Fe S-5 [-223.2]
4. Ni Alloy690 [-398.1]
5. Cu-Tramp Cu TrampMax [-232.9]

Could you please me inform me for the, material grade ( Gr.P11, Gr.P22 etc. ) or P.No. ( ASME IX) , as per results above?

What do those numbers even mean? Do you have a print or report on the measured chemical content? Have you tried comparing those numbers yourselves to a known or published spec (e.g. A335) to determine a possible match?
