Tinplate: Why it doesn't rust
Can someone tell me why doesn't tinplate rust? My son is doing an assignment on this.Rosie Robins
Rust is iron oxide, the corrosion product of iron when exposed to the oxygen in the air. Tin is not iron, so you cannot produce iron oxide from the corrosion of tin.

Because the layer of tin on the surface of the steel prevents atmospheric oxygen and moisture from contacting the steel. Scratch the layer of tin so that the steel is exposed to oxygen and moisture, and the steel so exposed will quickly rust.
