Galvanic Corrosion in mixed SS - Paper
Galvanic Corrosion in mixed SS - Paper
(OP)
I recall seeing a paper published some time ago describing sea water galvanic effects between some different austenitic and (I think) duplex stainlesses that showed a galvanic corrosion reversal between 316 and another SS. The author may have been Kearns. I cannot locate the paper. Can anyone help me?

Believe me, we tell people to NEVER put SEA-CURE tubes into a 316 tubesheet under any water conditions.
There are two factors, the 'weaker' alloy is suffering crevice corrosion, and then the corrosion products make the environment in the crevice severe enough to attack the stronger alloy.
The worst cases are with superferritics, but I have never seen the testing done with duplex grades. It could be similar.
