How Steel is Made: a Brief Summary of a Blast Furnace: There are two types of metals, ferrous & non-ferrous. Ferrous comes from, or contains iron, while Non-Ferrous does not contain iron. Some examples of ferrous metals would be mild steel, cast iron, high strength steel, and tool steels. Examples of non-ferrous metals would be copper, aluminum, magnesium, titanium, etc. To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added.
Alloys are metals that have been mixed together. Separately, they are hard and durable enough, but when mixed together they take on characteristics of the metals they are made from. For example, iron on its own is a strong metal, but when mixed with carbon, steel is formed.itanium. Iron/Aluminum. Low-density, corrosion-resistant metal; commonly alloyed with iron, aluminum, vanadium, and molybdenum, among other elements. While the above list is not all-inclusive, it gives shoppers an idea of the different metal alloys available to fit their needs.
