For those who may be relatively new here, this is the exectuive summary.
In the presence of vanadium, nitrogen is converted from an impurity into a cost-effective alloying element. The vanadium nitrides formed by vanadium and nitrogen are more stable and more finely dispersed than vanadium carbides. For that reason, vanadium strengthening is more efficient in the presence of nitrogen.
Reducing vanadium additions yields major cost savings. In the example below, equivalent yield strengths are obtained when either 0.10% vanadium is added as ferrovanadium or 0.06% vanadium is added as Nitrovan� vanadium. Using Nitrovan� vanadium reduces vanadium additions by 0.40 kg (0.90 lbs.) per metric ton of steel.
Note this saving is not some kind of trick due to the Nitrovan somehow containing more Vanadium than FeV from the start, this is with both Nitrovan and FeV being quoted and priced per Kg of contained Vanadium. The reduction of Vanadium required when using Nitrovan is purely down to the fact that the Vanadium is combined with nitrogen as Vanadium nitrides, and these are valuable strength improvers.
Apparently Nitrovan commands a premium of 5-10% over FeV, to be honest it should be nearer 40%.
