Manganese nitride iron is an indispensable alloy agent for the production of special alloy steel, stainless steel and heat-resistant steel, usually obtained by nitrogen filling with medium and low carbon manganese iron. Manganese nitride iron is mainly used as an additive in steelmaking production, can improve the strength of steel and other mechanical properties, refine grain, stabilize Austenite.

The main elements of manganese nitride have high content, low content of harmful impurities such as phosphorus, high utilization rate of nitrogen after adding melt, and low amount of addition. Nitrogen can improve the strength and plasticity of steel, expand the Austenite area, refine grain, improve its processing performance. Manganese nitride can replace some nickel to reduce costs.
