Ferroalloys
Graphite and graphite electrodes
Ferromanganese is an alloy whose main components are manganese and iron. The addition of manganese increases the hardness of steel, its anti-corrosion properties and resistance to tearing. Ferromanganese is widely used for alloying steel and its deoxidation, as well as for coating welding electrodes.
