Which metals can corrode iron and steel according to the galvanic series?

The galvanic series is a ranking of metals and alloys based on their electrochemical potential. When two different metals are in contact in a corrosive environment, the metal that is lower in the series will corrode faster than the one higher up, as they create a galvanic cell. Iron and steel, being relatively low on the galvanic series, are more susceptible to corrosion when in contact with metals that are higher in the series.

Silver, nickel, and brass are all positioned higher than iron and steel in the galvanic series, which means that when they come into contact with iron or steel, they can indeed cause the iron or steel to corrode faster. This makes them capable of galvanic corrosion of these lower-ranked metals.

In summary, the choice indicating that all of the listed metals can corrode iron and steel is accurate because each one (silver, nickel, and brass) has the potential to create a galvanic reaction that leads to the increased corrosion of iron or steel when in contact.
