Process to produce steel cutlery from iron ore chemical

Aug 21, 2020

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
