Steel 

Steel is an alloy of iron and a small amount of carbon. Carbon is the primary alloying element, and its content in the steel is between 0.002% and 2.1% by weight. Too little carbon content leaves (pure) iron quite soft, ductile, and weak. Carbon contents higher than those of steel make an alloy commonly called pig iron that is brittle and not malleable.
