Ferro silicon manganese Silico-manganese (SiMn) and ferromanganese (FeMn) are well-known members of the Mn alloys group. Silicomanganese is produced by carbothermic reduction of oxidic raw materials in electric submerged arc furnaces. Silico Manganese is an alloy with 60% to 70% manganese, 14% to 30% silicon, and 0.1% to 2.5% carbon. This alloy adds more silicon to improve some mechanical properties of steel.
