Ferrochrome nitride is widely used in steel containing nitrogen and oxygen converter smelting furnace. Nitrogen is the austenite formed element, it as an ingredient added Cr Mn and Cr Mn Ni stainless steel to replace the shortage of nickel. Widely used in stainless steel, heat-resistant steel, special steel smelting production of corrosion resistant steel, alloy steel, according to Huacheng metal net of nitrogen expanded austenite region, the effect is about 30 times of nickel, can partially replace the precious metal, reduce the production cost.
