Medium Carbon Ferro Manganese (MC FeMn) is product of the blast furnace containing 70.0% to 85.0% of manganese with carbon content from 1.0% max to 2.0% max.
It is used as a de-oxidizer for manufacturing of 18-8 Austenitic non-magnetic stainless steel for the introduction of manganese into steel without increasing the carbon content. By adding the manganese as MC FeMn instead of HC FeMn, approximately 82% to 95% less carbon is added to the steel. MC FeMn is also used for producing E6013 electrodes and in casting industries
