             fine quality fecr alloy for steelmaking                

1. Nantong Hanrui Industrial Co., Ltd. was founded in 2007 with total area of 25000 m2.

2. Our company possess large volume of natural vanadium resources .

3. Now our company has 40 sets of the advanced alloy production equipment.

4. The annual output of VNis 2400MT and 2000MT high purity vanadium.


Advantage for vanadium nitride

advantage

reason

Grain refinement and strengthening

Compared with VC, VN is better for the separation of V(C,N).

Reduce vanadium and lower cost

V(C,N)will cost fewer vanadium than that of VC, and this could reduce 40%, compared with Ferro-Vanadium.

Improve weldability, notch ductility and forgeability.

Use less carbon and less alloy addictive agent could reach the same strength level.

Effectively strengthening various carbon steel.

When temperature reach 1050 degrees Celsius, V(C,N) will have high solubility in austenite. Vanadium nitride work effectively in high, medium and low carbon steel.

Stain aging and shaping loss

Through choose Nitrovan 7 or Nitrovan 12, the proportion of V and N could be selected, avoiding nomadic nitrogen.
