Ferromanganese nitride is an important alloy product, mainly used in the production of High-strength steel, alloy steel, stainless steel, and automotive, shipbuilding, and aviation industry materials.

The characteristics of ferromanganese nitride
Ferromanganese nitride is usually obtained by filling nitrogen with medium and low-carbon ferromanganese and is very popular because of its high hardness, high strength, and good corrosion resistance.
Ferromanganese nitride is mainly used as a nitrogen additive in steelmaking production, which can improve mechanical properties such as the strength of steel, and refined grains, and stabilize austenite.
International Market Analysis of Ferromanganese Nitride
- Market scale: The demand for ferromanganese nitride in the global market is growing steadily. Data show that the demand for ferromanganese nitride in the global market will grow at a compound annual growth rate of about 3% in the next few years.
- Main market: The main market of ferromanganese nitride is the Asian region, especially China and India. These two countries consume about 80% of the global consumption of ferromanganese nitride. In addition, the European and North American markets also contributed a lot to the demand growth for ferromanganese nitride.
- Supply situation: The supply of ferromanganese nitride mainly comes from countries such as China, Russia, Ukraine, and India. Among them, China accounts for about 60% of the world’s total production.
- Price: The price of ferromanganese nitride fluctuates greatly, mainly affected by factors such as raw material prices, production costs, and market demand. At present, the price of ferromanganese nitride is relatively stable, but with the increase in market demand, the price is expected to rise.
The Preparation Method of Ferromanganese Nitride

Ferromanganese Nitride has Two Preparation Methods:
- Liquid nitriding method: Nitrogen is blown into the liquid medium and low-carbon ferromanganese in a closed container to saturate the alloy with gaseous or solid nitrogen-containing components.The ferromanganese nitride produced in this way has the advantages of high density, high strength, and high utilization rate of nitrogen when used in steelmaking. However, due to the low nitrogen content, it often cannot meet the requirements of steelmaking
- Solid-state nitriding method: Heating medium and low-carbon ferromanganese powder in a closed container, and fully contacting with nitrogen for nitriding. The interaction between the medium and low carbon ferromanganese in solid powder and the nitrogen decomposed from nitrogen or ammonia will generate a series of nitrogen-containing compounds, and the stability of these nitrides will decrease with the increase in temperature until they decompose. Therefore, this method should control the appropriate nitriding temperature.
Under normal circumstances, the 60 mesh below the medium and low carbon ferromanganese powder sealed in a container, in nitrogen and 650℃-1120℃ temperature of 4h-8h nitriding, can be obtained nitrogen 4-6% ferromanganese nitride.
Since the nitrogen content increases with the increase of the manganese content and increases with the decrease of the manganese carbide content, the nitrogen content of low-carbon ferromanganese with high Mn content is slightly higher than that of medium-carbon ferromanganese with low Mn content.
The density of the iron nitride product obtained in this way is small, if its melting density is increased, but the nitrogen content of the product will be significantly reduced.
