Because vanadium contains 0.15 to 0.25% of carbon.

I think Manganese MN should be the answer.

Vanadium (V) - It increases the yield strength and the tensile strength of carbon steels. Small amount of Vanadium increases the strength of steels significantly. It promotes fine grain and elevates coarsening temperature of austenite. The impact transition temperature increases when vanadium is added.
