Ferro manganese is the master alloy of Manganese and Iron with additions of carbon, Silicon and Phosphorous. It contains Mn content from 70 to 85%.
Phosphorus is a harmful impurity in ferro-manganese; the smelting of ferro-manganese low in phosphorus is however linked with considerable expenditures
Ferro manganese adds hardenability, hardness, ultimate strength, toughness and better yield limit to steel . Steels containing about 1 percent C and 11-13 percent Mn are distinguished by a high abrasion resistance.
The raw materials for Ferro manganese production consists of high grade manganese ore, coke, coal and with or without fluxes like dolomite, lime stone, quartz etc.
We supply the following grade of Ferro manganese
|70||2 max||8 max||0.35 max|
