6 · Iron ore is smelted in a blast furnace to produce pig iron, which contains high carbon content. Pig iron then undergoes refining by removing impurities and adjusting the carbon level to produce steel or cast iron. Alloying At the steelmaking stage, alloying elements like chromium, nickel, manganese, and molybdenum are introduced.
