Steel production is dependent upon coal and coke in steelmaking. Metallurgical coke, or met coke, is manufactured from blends of bituminous coal in a heated distillation process resulting in a non-melting carbon. Coke is made by one of two processes: by-product or non-recovery, also known as heat recovery.
In essence, steel is composed of iron and carbon, although it is the amount of carbon, as well as the level of impurities and additional alloying elements that determine the properties of each steel grade. The carbon content in steel can range from 0.1-1.5%, but the most widely used grades of steel contain only 0.1-0.25% carbon. 1  Elements such as manganese, phosphorus, and sulfur are found in all grades of steel, but, whereas manganese provides beneficial effects, phosphorus and sulfur are deleterious to steel's strength and durability.
