Steel is an alloy that mostly consists of iron and also has carbon content. Though Carbon is the most common alloying material for iron, various other alloying elements are also used, such as manganese, chromium, vanadium etc. Steel with increased carbon content can be made harder and stronger than iron, but such steel is also less ductile than iron.
