Ferro-silico-manganese is one of the main alloys containing iron, silicon and manganese.
It is used in the steel manufacturing process as deoxidising and alloyage agent.
Iron-based alloys are made harder, more durable and shock-resistant.
Ferro-silico-manganese of grade Mns 17, Mns 22, Mns 25 are manufactured according to the national standard of Ukraine, DSTU 3548-97.
