Stainless Steel

Stainless steel is mainly chromium alloy steel or nickel-chromium with the occasional addition of other elements like molybdenum or nitrogen to improve their oxidation resistance, to corrosion and or wear in different environments. The chromium inside the stainless steel easily oxidizes and forms a thin oxide layer that is stable, tenacious and resistant to corrosion. It forms a barrier and prevents corrosive products to attack the alloy deeply. This oxide layer also has the distinctive characteristic to reform itself when damaged. For a steel to be stainless, it must contain at least 10% of chromium.
