Galvanic Corrosion in Pump casing
Galvanic Corrosion in Pump casing
(OP)
A pump is being installed offshore, while pump casing is of Duplex Stainless Steel, casing bolts are of carbon steel(A193-B7 ). What is the possibility of galvanic corrosion for this combination due to moisture in marine atmosphere?

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Higher strength than A193-B8M (316) may be required, and B7 is the economical option. Don't go to lower strength hardware without checking with the manufacturer.
