Sorry gents, more info.
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.
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.
