[MW:701] Re: 698] Re: PMI TESTING OF SS 304L

XRF can only detect elements with atomic numbers greater than 21 i.e.
starting with Titanium onwards. Therefore, it cannot quantify C, S, P, etc.
So, it can tell the difference between SS304 and SS316, but not SS316 and
SS316L.

OES can detect all the elements including carbon, so it can be used very
conveniently for segregating even SS316 and SS316L.

that's one of the main diff between OES and XRF analysers, where XRF
analysers can't detect %C and trace elements like S,P etc....

DEAR PINAKIN,

THANKS FOR THE REPLY. IN THAT CASE HOW TO DIFFERNTIATE SS304 FROM 304L AND
SS316 FROM 316L. IF WE CAN NOT ANALYSE CARBON %.

REGARDS,

Dear Dave,
PMI can tell you the % of the contains like Ni, mo etc. Based on this % we
can check our requirement.

Probably spectro isort by Amtek can detect C, (thou I have not
used it), you can try at www.spectro.com

Also Arcmet930 by Metorex can detect C

DEAR MEMBERS,

CAN ANYBODY TELL ME WHAT TECHNIQUE SHOULD BE USE TO PERFORM PMI OF
SS304L. SINCE CARBON ANALYSIS IS VERY VERY IMPORTANT.
