Any metal which can get oxidised in the presence of oxygen from the air and water.

Yes, steel rusts and over time it will decay.
a nail rusts
steel rusts fastest in salt water.. wonder why??? because salt water has sodium which can react to iron in steel.

Steel oxidises fastest
This may be wrong but I am 90% sure that steel rusts quite easily. Obviously people do not want to buy a car that rusts quickly.
Rusting is an oxydation reaction.
There is only one metal that rusts and that is iron and its alloys such as steel. All other metals corrode. No, iron is not iron after it rusts. It is now called iron oxide and will disintegrate if left unchecked . That is why we paint our gates with Blackstar Rust Converter and most electronics are coated with gold or a green varnish to prevent reaction with the air.
