Silicon Manganese Nitride

Silicon Manganese Nitride is composed of Si3N4, Mn5N2, and some non-nitrided ferrosilicon,non-nitrided silicomanganese and less other mixtures. It is commonly pressed into briquettes before sintering in current process, and is rust red after finished.

     

Specification

Chemical Composition ( % )
Mn Si N C S P
Type A 30~55 15~25 10~25 =1.0 =0.03 =0.1
Type B 10~20 38~45 26~33 =1.0 =0.03 =0.1
Particle size 20- 50mm lumps or briquettes

Applications:

Top-grade high-quality formed and amorphous refractories

In alloying production of high-strength low alloy steel, steel bar and stainless steel, after matched with FeV or VN, it can promote absorption of nitrogen in molten steel by manganese therein to increase content of nitrogen in steel, and can take larger effect of refining grains if matching with microalloying elements. The silicomanganese nitride mainly functions as nitrogen enhancing agents for oriented silicon steel, high-strength steel (as HRB400) and forging.
