WebStainless steel is known and used for its ability to resist corrosion. Ordinary iron-carbon steels corrode easily in air. Oxygen combines with iron to produce a red oxide known as rust. Although chromium corrodes in a similar manner, its oxide, Cr2O3 forms a hard surface layer preventing oxygen from reacting with iron. WebAll stainless steels consist of at least 10.5 % of chromium by weight and act as a shield. Chromic Oxide is also used in automotive finishes. It has a metallurgical use, like manufacturing chromium metal and aluminum-chromium master alloys. It is a catalyst for organic and inorganic reactions.
