Galvanic Corrosion of Ferritic Stainless Steels in Seawater

Source

Galvanic behavior of stainless steels in seawater is difficult to predict because of their susceptibility to localized corrosion. This susceptibility can be either enhanced or eliminated depending on the particular galvanic couple.

This paper deals with seawater corrosion of several ferritic stainless steels in galvanic couples. Methods of predicting their behavior are described based on electrochemical polarization measurements, various laboratory tests, and actual immersion in seawater.

Results of electrochemical and laboratory tests are compared with those obtained in seawater. The validity of each of the test procedures is discussed with regard to alloy development and designing materials systems.
