Nitrogen displaces oxygen that originally came from Earth's atmosphere. In the absence of oxygen, steel can not rust.
Rust is most of all 'metal oxide' which is chemically formed by reaction of certain metals (not all) with oxygen (gas, 20% in air)
Nitrogen gas (N2) makes up 79% of air (so more than 70%).
A diatomic gas.
