Any water makes iron rust. Rust is iron oxide. It happens when water allows the oxygen to dissolve in it and get to the surface of the metal. Salt water has dissolve salts in it which makes it work faster.

Salt water contains Na+ & Cl- ions which are highly reactive with iron to form FeCl2 .So iron rust faster in salt water.
