Dissimilar welding of 317Lss (P-8) to SA516-70 (P-1)

Dissimilar welding of 317Lss (P-8) to SA516-70 (P-1)

(OP)
Looking for recommendations on filler metal for welding 317L stainless to SA516-70 for a 650 deg F application.  Typically use 309 for carbon to stainless joints, but would like to make sure that this particular dissimilar joint doesn't pose any additional issues.

Inconel 82 or 182.

RE: Dissimilar welding of 317Lss (P-8) to SA516-70 (P-1)

Given the higher Mo content of 317L the use of the Ni-Cr-Mo fillers would be a good idea.
