the content of the main elements nmnfe is high, the content of harmful impurities is low such as phosphorus, the utilization rate of nitrogen is high after it add to the melt, and the addition is less. nitrogen can improve the strength and ductility of steel, expand the austenite area, grain refinement, and improve the processing properities. it is mainly used in the production of high-strength steel, alloy steel, stainless steel.
