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.here are two types of metals, ferrous & non-ferrous.
