Chromium in stainless steel

The factor that is primarily responsible for the self-passivation mechanism of stainless steel is chromium.

In contrast to carbon or low alloy steels, stainless steels must, according to the EN 10088-1, have a minimum chromium content of 10.5% (by weight) and maximum of 1.2% carbon.

The corrosion resistance of chromium steels can be enhanced by alloying them with other elements, such as nickel, molybdenum, nitrogen, titanium or niobium. This provides a range of steels with corrosion resistance for a wide range of conditions. Alloying also enhances other useful qualities of the steel, such as formability, strength and heat resistance.
