ferromanganese, all you need to know about it
High carbon ferromanganese (HCFeMn) is an alloy composed primarily of manganese (around 70-80%), carbon (6-8%), and silicon (1-2%). It is a type of ferroalloy, which is an alloy of iron and one or more other elements, used in the production of steel and other alloys. The primary use of high carbon ferromanganese is in the production of steel.
