of course it is the iron screw because it is made up of minerals that rust faster then metal
iron
Fe2O3 Iron Oxide time is varying but if the metal is hotter rust occurs faster.
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
Liquids do not rust, iron does, rust is Hydrated Iron (III) oxide, so the only substance which can rust iron is water
Rust is formed as a result of oxidation of iron (Fe) metal.
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.
----
Water, especially when it contains dissolved salts or minerals, can accelerate the rusting process of a screw. This is because water provides the necessary conditions for the electrochemical reaction between iron and oxygen to occur, leading to the formation of rust.
Rust is the oxidation of the cast iron. Oxygen in the air combines with the base metal to create the rust. The rust protects the metal underneath. Cast iron is not "reacting" to rust. It is participating in FORMING the rust. ************** previous answer below *************** Very well as the rust actually protects the base metal
Iron is the only metal that can rust. The usual term for the destruction of a metal by oxidation is corrosion, and 'rust' or 'rusting' is the term for corrosion specific to iron and its compounds.

Rust is the oxidation of iron metal or just iron. Rust is actually iron oxide. It's chemical symbol is Fe2O3.
