Steel - Raw Materials - Iron, Carbon, Ore, and Oxygen

There are several basic elements which can be found in all commercial steels. Carbon is a very important element in steel since it allows the steel to be hardened by heat treatment. Only a small amount of carbon is needed to produce steel: up to 0.25% for low carbon steel, 0.25-0.50% for medium carbon steel, and 0.50-1.25% for high carbon steel.
