Ferromanganese

Ferromanganese is an iron-manganese alloy widely used in steelmaking as a deoxidizer, desulfurizer, and alloying additive. It is produced by smelting manganese ore with coke and iron ore in electric arc furnaces or blast furnaces. With a strong affinity for oxygen, manganese effectively removes oxygen from molten steel and improves the steel's hardness, ductility, toughness, and wear resistance.
◉ Product Description

Ferromanganese – Product Overview

Ferromanganese is an iron-manganese alloy widely used in steelmaking as a deoxidizer, desulfurizer, and alloying additive. It is produced by smelting manganese ore with coke and iron ore in electric arc furnaces or blast furnaces. With a strong affinity for oxygen, manganese effectively removes oxygen from molten steel and improves the steel's hardness, ductility, toughness, and wear resistance.

Based on carbon content, ferromanganese is classified into three main categories: High-Carbon, Medium-Carbon, and Low-Carbon.
