The main difference between iron and steel lies in the carbon content: steel is iron with a carbon content between % and 1,075%. Steel retains the metal characteristics of iron in its purest form, but the addition of carbon and other elements either metallic or non-metallic improves its physical-chemical properties, especially its resistance. There are many types of steel
