Manganese Nitride MnN powder
Product Description
Manganese nitride is formed from manganese powder by reacting with nitrogen. Manganese nitride, whose chemical formula is MnN, is a compound of manganese and nitrogen. The manganese nitride powder produced by Huarui has high content of main elements and low content of harmful impurities, which can improve nitrogen utilization rate after adding into melt. Manganese nitride can be slowly decomposed by water and dissolved in a nonoxidizing dilute acid to form ammonium salts. Manganese nitride is mainly used as a nitrogen additive in steelmaking production, which can improve the strength of steel and other mechanical properties, refine grain, and stabilize austenite.

Application
1. For the production of special alloy steel, high-strength steel, stainless steel, heat-resistant steel products.
2. It can be used as an additive in steel making, so that the steel has excellent properties such as strength, toughness and creep resistance.
3. Used in the field of high nitrogen steel smelting.
Quality control system
Huarui has strict quality management system. We test our products first after we finish our production, and we test again before every delivery, even sample. And if you need, we would like to accept third party to test. Of course if you like, we could provide sample to you to test.
Our product quality is guaranteed by Sichuan Metallurgical Institute and Guangzhou Institute of Metal Research. The long term cooperation with them can save a lot of testing time for customers.
