Preventing galvanic corrosion between aluminum and stainless steel

Aluminium and stainless steels (austenitic, duplex and super duplex stainless steels) are sufficiently different in terms of their galvanic potential for galvanic corrosion to occur if they are inadvertently coupled. In this couple, the aluminium would act as the anode in an electrochemical cell and be preferentially attacked.

How to Prevent Galvanic Corrosion Between Carbon and Stainless Steel

Galvanic corrosion is the reason connecting carbon and stainless steel can lead to problems. Galvanic corrosion is when one metal causes another metal to corrode and break down. For this corrosion to start, there need to be three things: an anode (one metal), a cathode (a second metal), and an electrolyte (water is a common one).
