This innovation meant that, finally, iron ore from anywhere in the world could be used to make steel. Not surprisingly, steel production costs began decreasing significantly. Prices for steel rail dropped more than 80% between 1867 and 1884, as a result of the new steel producing techniques, initiating the growth of the world steel industry.

And speaking of those tools, unlike wood, iron can handle high temperatures, allowing us to build everything from fire tongs to furnaces out of it. In contrast to most substances, you can also magnetize iron, making it useful in the creation of electric motors and generators. Finally, there certainly aren't any iron shortages to worry about.

The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal and convert it into high-quality steel.

Iron has long been the preferred catalyst for ammonia production. Using a method known as the Haber Process, nitrogen and hydrogen gasses can be passed over four beds of catalytic material to convert at a rate of almost 97%. Finely ground iron powder is the most cost-effective, easy to obtain catalyst for use in this process on an industrial scale.
