    This process made steel production cheaper, efficient and easier. Steel is made by putting iron through a process known as smelting, where iron is extracted from the iron ore and excess oxygen is removed and the iron is combined with chemical partners such as carbon. Steel, compared to pure iron is more rust resistant and has a better weldability.
