What Is The Difference Between Iron And Steel Blacksmith U

Iron is a chemical element that can be found in nature. There is lots of iron within the Earths crust. Steel is an alloy, which means its made from two or more different elements. One of which will be iron. Humans have been using iron for thousands of years. As far back as 1,200 BC. Discovery and widespread production of steel came much later.
