manganese as an additive in the steel making process

  • An Overview of Steelmaking Process ..

    Steelmaking process involves the production of steel from iron ore and scrap. In this process various impurities such as silicon sulfur nitrogen phosphorus and excess carbon are removed from the sourced iron. And to produce different grades of steel alloying elements such as nickel manganese chromium and vanadium are added.
