[MW:25819] Using ER316L instead of ER308L to weld 304L to 304L

Dear experts,

we have situation is here one of our welder selected wrong filler material,

To weld 304L to 304L as per wps it was selected ER308L.

One of our welder welded with ER316L we have found this after completion of weld in the PMI results where MO content is showing 2.0%.

Is that acceptable to weld higher grade electrode for 304L piping. 

Regards
Reddy.M
