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.

At the request of the consumer, ferromanganese is produced with a mass fraction of manganese in the FMn70 grade of at least 70%, in the FMn78 grade - at least 78%.
The designation of the ferromanganese grade includes the base of the alloy, the mass fraction of carbon, silicon and phosphorus.
