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?
