Rusting is an oxidation process in which iron reacts with oxygen in the presence of water or moisture. The product formed is hydrated iron oxide, commonly called rust. Dry iron exposed only to oxygen rusts much more slowly because moisture helps the electrochemical reaction proceed. Thus both oxygen and moisture are the principal conditions required for normal rusting of iron.
