Super Duplex (S32760) and 15-5PH Galvanic Corrosion
Super Duplex (S32760) and 15-5PH Galvanic Corrosion
(OP)
Hi all,
Could you please tell me whether there is a galvanic corrosion risk (or how to calculate the corrosion potential) between the following stainless steels:
- Super Duplex (S32760)
- 15-5PH Galvanic Corrosion
Many thanks,
Lukasz

15-5PH will not be quite as good as 304, so if they are coupled, and there is not something done to suppress it I would expect the 15-5 to suffer galvanic accelerated corrosion.
One option is to coat the superduplex.
