STAINLESS STEELS

Stainless steels are iron-chromium-carbon alloys whose main property is resistance to corrosion resulting from their ability to passivate spontaneously (that is, to become covered with an invisible layer of oxides that protects the metal underneath from corrosion) when chromium content is higher than 10,5% roughly.
Besides their excellent resistance to corrosion, stainless steels also have good oxidation resistance, high temperature strength and very good toughness at low temperatures.
