Steel Making Process

Steelmaking is the process of producing steel from iron ore andor scrap In steelmaking impurities such as nitrogen silicon phosphorus sulfur and excess carbon most important impurity are removed from the sourced iron and alloying elements such as manganese nickel chromium carbon and vanadium are added to produce different grades of steel
