Although tin is used to coat steel cans, it does not act as a sacrificial metal. Instead, it acts only as a barrier to stop air and water reaching the surface of the iron or steel. The tin layer may actually make rusting happen faster if it gets scratched, because then iron loses electrons in preference to tin.
