Stainless steel

Stainless steel (or stainless steels) are iron alloys that share similar mechanical properties to carbon steels and have a high resistance to corrosion, especially in moist air or in fresh water.

The ability to resist corrosion is due to the presence of alloying elements, mostly chrome, which is capable of passivating, i.e. to become covered by a thin and adherent layer of oxides with a thickness of a few atomic layers (in the range of 3-5 × 10−7 mm), which protects the metal underneath from external chemical agents.

Stainless steels generally have a carbon content of less than 1.2%. The minimum content of “free” chromium, i.e. not combined with carbon, ranges between 11-12% for the continuous “passivating” oxide layer that protects against corrosion to form. The chromium in the alloy, by combining with carbon, may form chromium carbide, which restricts the capability of the alloying element of forming oxides and thus of passivating.
