Product characteristics

Nano vanadium nitride (VN) is prepared by aerosol ablation method. The product has uniform particle size distribution and large volume production. It can be widely used in cemented carbide. It has high surface activity, can be well dispersed in the alloy material, and plays a role of alloy dispersion strengthening. Vanadium nitride, also known as vanadium nitrogen alloy, is a new type of alloy additive, which can replace FEV in the production of microalloyed steel. The addition of VN to steel can improve the comprehensive mechanical properties of steel, such as strength, toughness, ductility and thermal fatigue resistance, and make the steel have good weldability. At the same strength, the addition of nano VN can save 30-40% of the amount of vanadium and reduce the cost.

Product application

V-N alloy can be used in structural steel, tool steel, pipe steel, steel bar and cast iron. When V-N alloy is used in high strength low alloy steel, it can effectively microalloy V and N at the same time, promote the precipitation of C, V and N compounds in steel, and play a more effective role in precipitation strengthening and grain refinement;

VN has very high thermal and chemical stability and strong mechanical properties. It is widely used in cutting tools, abrasives and structural materials. It is also a good catalyst with high catalytic activity, high selectivity, good stability and anti poisoning performanc
