Why does rust form on stainless steel?

Stainless contains a minimum of 10.5% chromium. This chromium reacts quickly with surrounding oxygen to form a thin oxide layer on the steel’s surface. Unlike iron oxide, which often is in the form of flaky and corrosive rust, the chromium oxide clings to the steel. … This film gives stainless its rust-resistance.

How long does it take metal to rust in salt water?

Initial exposure to clean seawater is crucial to the long-term performance of copper-nickel alloys. The initial film forms fairly quickly over the first couple of days but takes 2–3 months to fully mature. The time depends on the temperature; the higher the temperature, the faster the film is developed.
