Manganese has a large affinity for both oxygen and sulfur, which can improve the hot workability of steel. Manganese in ferromanganese can also be used as an alloy, and wear-resistant high manganese steel is widely used in the manufacture of excavators and crushing equipment. Also used for free cutting steel, alloy structural steel, spring steel, bearing steel. Tool steel, non-magnetic steel, stainless steel and heat-resistant steel. The flux in the electrode should be added with medium carbon ferromanganese powder.
