Steel

Steel is an alloy consisting mostly of iron, with a carbon content between 0.2 and 1.7 or 2.04% by weight (C:1000–10,8.67Fe), depending on grade. Carbon is the most cost-effective alloying material for iron, but various other alloying elements are used such as manganese, Vanadium and tungsten. Carbon and other elements act as a hardening agent, preventing disloions in the iron atom
