Vanadium-Nitrogen Alloy is a new type of alloy additive, it can substitute Ferro Vanadium used in the production of Micro alloying-steel. Nitride Vanadium adding to the steel can increase the strength, tough, tractility, anti-thermal fatigue etc. It also can make the steel be able to fulfill solderability To attain the same strength, adding Nitride Vanadium could save 30-40% of Vanadium, thereby saving the cost.
