Steel is an alloy of iron and a number of other elements, mainly carbon, that has a high tensile strength and relatively low cost.

Early forms of steel have existed since around 1800 BC, and it has subsequently be used through history by the Greeks, Romans, Indians and Chinese. However, British engineer, Sir Henry Bessemer was the first to develop a cost-efficient method for producing steel, and it was first mass produced for the manufacture of railway tracks.
