Ferro Manganese Powder (FeMn):

Ferromanganese is an alloy of iron and manganese containing usually about 80% manganese.

Ferromanganese is used mainly to counteract the bad effects of sulfur. It also acts as a deoxidizer and combines with sulfur, thereby improving the hot-working properties of the product. It imparts metallurgical properties such as increased strength, hardness toughness and hardens ability.
