Silicon Manganese Nitride

Nitrogenation in some micro-alloyed steels can fully exploit the role of microalloying elements, saving their usage and effectively reducing production costs. Therefore, nitrides are excellent additives in metallurgical production. In recent years, the special effects generated by the interaction between nitrogen and alloying elements have gradually gained attention, leading to the development of a series of high-nitrogen iron alloys: nitrided vanadium, nitrided manganese, nitrided chromium iron, nitrided silicon iron, etc.

However, these nitriding alloys generally face some issues: for nitrided vanadium, the limited vanadium resources result in high production costs; the use of nitrided niobium iron requires an increase in rolling temperature, which much domestic rolling equipment cannot meet; nitrided manganese and nitrided chromium iron have nitrogen mass fractions less than or equal to 6%, limiting their application value; titanium in nitrided titanium iron is highly active and difficult to control, resulting in low yield in molten steel. It wasn’t until the development of manganese silicon nitride (MnSiN) alloy that the true effectiveness of nitrides as smelting additives was realized.

The main substances in manganese silicon nitride alloy (MnSiN) are manganese nitride (Mn5N2) and silicon nitride (Si3N4). Manganese plays roles such as deoxidation, desulfurization, and alloying in steelmaking. Manganese can eliminate or reduce the hot brittleness caused by sulfur, thereby improving the hot working performance of steel; it can also refine pearlite grains and improve the strength of pearlite steel while enhancing the hardenability of steel. Silicon nitride exhibits high-temperature thermal stability, thermal shock resistance, resistance to cold and hot shock, chemical stability, good electrical insulation, and hardness. Manganese silicon nitride alloy combines the special properties of silicon nitride and manganese nitride. Moreover, after combining silicon, manganese, and nitrogen, its performance becomes even more superior.

Specification of Silicon Manganese Nitride:

38-42 25-30 ≤1 ≤0.05 ≤0.1 10-15
35-40 20-25 ≤1 ≤0.05 ≤0.1 10-15
32-36 18-22 ≤2 ≤0.05 ≤0.1 19-23


Particle size: 0-3mm, 5-50mm, can be customized according to customer requirements.

Five preparation methods for manganese silicon nitride:

Vacuum sintering method, secondary nitriding method, microwave synthesis method, high-temperature self-propagating synthesis method, and atmospheric pressure one-step synthesis method. Existing preparation processes can be optimized and improved by simplifying operations, shortening reaction time, and reducing production costs. In the future, further exploration and improvement will continue in these aspects.

Manganese silicon nitride is a new type of steel additive with excellent performance and application advantages compared to conventional nitriding alloys. It possesses good resistance to thermal shock, thermal conductivity, chemical stability, and minimal thermal expansion. Its strong microalloying effect and nitrogenation effect have been widely applied in the fields of oriented silicon steel, HRB400 grade and above thread steel bars, etc., showing great market demand.
