The terminology isn't totally perfect since that terminology predates our understanding of elements, atoms, and crystals that we now understand define these materials. The main reasons for the popularity of steel are the relatively low cost of making, forming, and processing it, the abundance of its two raw materials (iron ore and scrap), and its unparalleled range of mechanical properties.
