Steel is an alloy of iron with other elements like C, Cr, Ni etc. High carbon steel contains more % of C than the other elements. Adding carbon increases the strength of iron because carbon atoms can fit into the interstitial crystalline lattice sites of the body-centered cubic (BCC) arrangement of the iron atoms.As a result the lattice becomes close packed and reduces the dislocations.As the dislocations are minimized,iron becomes more hard and strong.
