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

[weldgal]

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.

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