Ferro Manganese
Ferro manganese is made by smelting manganese ore in a blast furnace or electric furnace. It is a commonly used deoxidizer in steel industry, and manganese can also desulfurize and reduce the harmful effects of sulfur. Therefore, almost all kinds of steel and cast iron contain a certain amount of manganese. As an important alloying agent, ferro manganese is also widely used in alloy steels such as structural steel, tool steel, stainless heat-resistant steel and wear-resistant steel.

As an important alloying agent, ferro manganese is also widely used in alloy steels such as structural steel, tool steel, stainless heat-resistant steel and wear-resistant steel.The manganese element is essential in the steel industry. About 80% of manganese is used as a steelmaking deoxidizer, which can refine the grain of steel and improve the hardenability of steel;Manganese is also commonly used as an alloying agent to enhance the atmospheric corrosion resistance and improveforgeability and rollability of the steel. Wear-resistant high-manganese steel is widely used in theproduction of equipment components for excavators and crushers. When smelting stainless steel, manganese can replace the scarce metal nickel.
Main categories of ferro manganese alloys: high-carbon ferro manganese, medium-carbon ferro manganese, and low-carbon ferro manganese.
