Rather, iron ore is smelted and refined to produce steel. The production steps that transform iron ore into steel add energy to the metal. Steel, like most metals except gold and platinum, is thermody-namically unstable under normal atmospheric conditions and will release energy and revert back to its natural state—iron oxide, or rust.
