Chromium

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> To obtain steel from pig iron, it needs to go through further refining. Pig iron is melted, while the impurities are removed through oxidation. Manganese, nickel and chromium are added to improve the steel’s properties. The steel produced through these processes are shaped through rolling, pressing, casting, and forging.
