Vanadium Content in 4330V Steel

  1. Nov 13, 2015 #1
    Hi all,

    Hope I'm posting this in the right forum! I have some questions with regards to 4330V steel. This is a Vanadium-modified 4330 steel, with Vanadium contents ranging from 0.05 - 0.15%.

    I work for a company that builds tools for the mining industry, and our steel suppliers are divided on the issue of Vanadium content. Some say it should be near the 0.05% minimum, others say it should be at or near 0.15%.

    The problem is that nobody here understands the impact of Vanadium in this steel and how (if at all) it affects its properties.

    Any input?

    Vanadium is a carbide and nitride former, so it strengthens steels by dispersion-strengthening. It also affects grain structure.

    It seems that a number of suppliers prefer a nominal content of about 0.07 or mid range of 0.05 to 0.10%. There could be synergistic effects with Cr and Mo contents.

    It is also important to consider the heat treatment and hot/cold working which will affect the microstructure.

    Effects of V on steels:

    It's best to look at different sources.

    One might try to obtain some samples with one on the low end of the V range and one on the high end and compare tensile strength, hardness, and impact strength.
