Filler alloy for 20cb-3, UNS N08020
(OP)
Looking for the filler alloy for Manual GTAW welding of 20cb-3, UNS N08020. Is there a book or data sheet that I can find all of these items in?? Our WPS says use 316L. My predesessors have shown them selves to be less than thorough and accurate.

Is Carpenter still using rare earth additions for deoxidation? There used to be enough variation in residual rare earth content from heat to heat that weldabiltiy of 20Cb3 was a real issue. We use generic alloy 20 (or 20Nb3 as we jokingly call it).
