The Self-Protecting Superpower of

Stainless steel is an iron alloy that is resistant to corrosion and rusting. But what actually makes stainless steel stainless?

Stainless steel contains elements such as iron, manganese, silicon and carbon, to name a few, but by definition must contain at least 10.5% chromium.

These elements, with chromium playing the most dominant role, react with the oxygen in the air to form a complex chrome-oxide surface layer that is practically invisible – thinner than the wavelength of light – but strong enough to prevent further oxygen from staining and rusting the surface.

Additionally, when higher levels of chromium or other alloying elements such as nickel and molybdenum are added, the protective power of this surface layer is enhanced and the corrosion resistance of the stainless material is improved.

To sum it up, stainless steel self-resists rust and corrosion by utilizing its ability to form a protective barrier against corrosive attacks of oxygen and water.
