Chemically, it generally behaves similar to iron. Manganese in metal form is oxidized outdoors and rusts in a humid environment. It burns with air or oxygen at high temperatures, similar to iron.
FerroMangan is generally used in steel production. Its main use is for hardening of steel, desulfurization by forming MnS compound and also as a deoxidant.
FerroMangan is also one of the elements that provide strength properties in gray cast irons.
