An iron alloy can only contain up to 2% carbon and still be called steel. If it contains more than 2% carbon, it’s known as a different product called pig iron. Melting down iron ore with coke to create pig iron is an easy way of processing it, and is often an intermediate step in the refining process.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks ...
