How does iron become steel
WebMaking steel Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route. WebIn order to convert wrought iron into steel—that is, increase the carbon content—a carburization process was used. Iron billets were heated with charcoal in sealed clay pots that were placed in large bottle-shaped kilns holding about 10 to 14 tons of metal and about 2 tons of charcoal.

Australia exports almost 900 million tonnes of iron ore each year, but only makes 5.5 million tonnes of steel ... Iron is commonly found in the Earth's crust in the form of an ore, usually an iron oxide, such as magnetite or hematite. Iron is extracted from iron ore by removing the oxygen through its combination with a preferred chemical partner such as carbon which is then lost to the atmosphere as carbon dioxide. This process, known as smelting, was first applied to metals with lower melting points, such as
