The Properties and Effects of Manganese as an Alloying Element

Medium- and low-carbon ferromanganese is a product of low carbon and silicon content is obtained by fusing manganese ore, coal, and lime flux in a furnace, thus forming a MnO-rich melt. This is later contacted with low-carbon silicomanganese or silicomanganese.

Ferro Manganese High Carbon is an alloy of iron and manganese with high carbon contents, usually 6-8% w/w. High carbon Ferro Manganese is usually produced in arc furnace from manganese ore and coke in specified ratios. The widespread shift toward duplex refining practices such as the AOD, CLU, etc., has led to greatly increased use of high-carbon ferromanganese.
