一.Features:
Nitrided ferro manganese is abtainted through using the medle and low carbon Mn Fe to replace Nitrogen, As a alloy additives of nitrogen and manganese.
二. Application:
it mainly used for special alloy steelhigh strength steelstainless steelheat-resistant steels production. It is the essential alloying agent of Automobile ship building and aviation industrial materials too. Nitrogen can enhance the steels strength ande plasticity, expanded austenite zone, refine grain and improve the processing performance.
