Re: [MW:25826] Using ER316L instead of ER308L to weld 304L to 304L

ER 316L is often used to weld 304L material and can provide superior corrosion resistance; however, 

in some corrosive environments it may be highly detrimental (most notably in environments subject 

to metal dusting of 316). ER308 is the more economical choice especially when taking into account 

today's high molybdenum cost.

-Since ER316L has the same F number with ER308L as per ASME Section IX , You can use it by issuing a new WPS based on Your PQR.

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
