Steelmaking Wikipedia

Steelmaking is the process of producing steel from iron ore and/or 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 .

Nickel processing | Britannica

Nickel processing. In stainless steels, nickel improves the stability of the protective oxide film that provides corrosion resistance. Its major contribution is in conjunction with chromium in austenitic stainless steels, in which nickel enables the austenitic structure to be retained at room temperature.
