IRON AND STEEL INDUSTRY

U.S. Steel's ten divisions reflected the diversity of steel products made at that time, including steel wire, steel pipe, structural steel (for bridges, buildings, and ships), sheet steel (which would go largely for automobile bodies in subsequent decades), and tin plate (once used for roofing shingles, it would increasingly go to make tin cans).

Steelmaking - Wikipedia

Steelmaking is the process for producing steel from iron ore and scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to produce different grades of steel .

How steel is made - a summary of a Blast Furnace

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.
