Manganese: No Longer Just an Input on SteelWajd Boubou
Industrial and Metallurgical Steel produced from iron contains a high amount of oxygen and some sulphur. Manganese plays a key role because of its ability to combine with sulphur, and its powerful deoxidation capacity. Without manganese, steel would have a low melting point. Around 30% of the manganese used today is for this purpose.
