  • Galvanic Corrosion – PennEngineering

    Galvanic corrosion potential is a measure of how dissimilar metals will corrode when placed against each other in an assembly. Metals close to one another on the chart generally do not have a strong effect on one another, but the farther apart any two metals are separated, the stronger the corroding effect on the one higher in the list.

    In this case, the clear winner is stainless steel. Unlike standard steel, stainless steel has a property known as "passivation." This refers to its ability to form a layer of oxide on itself in response to contacting air.[2] This layer of oxide protects stainless steel from corrosion and rust, allowing for a longer lifespan than regular steel.

    Stainless steels resist corrosion because they have self-repairing "passive" oxide film on the surface. As long as there is sufficient oxygen to maintain this film and provided that the level of corrosives is below the steel's capacity of the particular material to repair itself, no corrosion occurs.
