manganese nitride

Manganese,Rare metal

The research of manganese nitride master alloy products has important practical significance and economic value for the deep processing industry of manganese metal. Because of the various functions of manganese and nitrogen, manganese and nitrogen elements should be added simultaneously in the process of making high strength steel, stainless steel and heat-resistant steel. When adding manganese and nitrogen in the form of elementary substance, there are some shortcomings, such as low solubility, low density, difficult to add and difficult to control the amount of nitrogen added. However, when added in the form of nitrogen and manganese compounds, it is not only easy to be added, but also the utilization rate of manganese and nitrogen is high. Therefore, it is of great significance to study the preparation process of manganese nitride. At the same time, the market prospect of manganese nitride products is bright.

Nitrogen content of high nitrogen manganese nitride products is up to 8%. It is used in the field of high nitrogen steel smelting, as an additive in steelmaking, and endows steel with many excellent properties, such as high strength, toughness and creep resistance.

Manganese nitride is mainly used to manufacture special steel in steel-making industry. Ferromanganese is used as desulfurizer and deoxidizer in iron and steel production. If 2.5-3.5% manganese is added to the steel, then the low manganese steel is as brittle as glass and breaks at a stroke. However, if more than 13% manganese is added to make high manganese steel, it becomes both hard and tough. When high manganese steel is heated to light orange, it becomes very soft and easy to process.
