Vanadium-nitrogen alloy is a new kind alloy additive that can replace ferrovanadium for microalloyed steel making. Vanadium nitride added to the steel can improve the overall strength, toughness, ductility and thermal fatigue resistance of steel and other mechanical properties, making the steel good weldability. With achieving the same steel strength, adding vanadium nitride can save vanadium amount by 30-40%, thereby reducing costs.
Advantages & Applications
- More effective and intensive grain refinement than ferrovanadium.
- Vanadium-nitrogen alloy can save 20-40% vanadium, compared with vanadium iron under the same strength condition.
- The yield of vanadium and nitrogen is stable, reducing the fluctuation of steel performance.
- Easy to use, low loss. High-strength moisture-proof packaging, can be directly put into the furnace.
- Vanadium nitrogen alloy can be used for structural steel, tool steel, pipe steel, steel and cast iron.
- Vanadium-nitrogen alloy used in high-strength low-alloy steel can promote the precipitation of carbon, vanadium and nitrogen compounds in steel, and more effectively play the role of sedimentation enhancement and grain refinement.
