Galvanic corrosion inconel/8630
(OP)
Is there a problem with coupling Inconel 625/825 with AISI 8630 in seawater?
I dont think there is but I need to tie it down with facts.
Difference in voltage is -0.2, 8630 has largest area.

At depths where oxygen content is very low, for example, this may pose no risk to either alloy (it obviously won't be a concern for the Nickel alloy). You do not say if the steel is coated - why would that not be the case anyway even if there was no dissimilar metal configuration?

Exterior of 8630 is painted,interior is uncoated.
However where the inconel and 8630 are in contact it is a trapped volume with no replenishement of electrolyte.
