Vanadium-nitrogen alloy is an excellent steelmaking additive, which can improve the comprehensive mechanical properties of steel and make the steel have good weldable properties. Compared with the use of iron vanadium, it can save 20% to 40% vanadium. Compared with the use of iron vanadium, vanadium resources can be saved by 20% to 40%, thus reducing the production cost of steelmaking. Taking the construction industry as an example, the use of vanadium nitrogen alloying technology to produce new tertiary steel, due to its increased strength, not only enhances the safety of the building, earthquake resistance, but also can save 10% to 15% steel than the use of secondary steel.
