Interesting read on Twitter regarding the new steel standard!
From reading a bit more about it (and finding some info on the AVL forum), it looks like they are discontinuing the lower grade steel (Grade2) that has a lower reinforcement requirement. Which means that the minimum Vanadium content would be 0.06% (grade 2 was 0.03%).
This could actually be a pretty big story in the end! Could be huge if VR8 manages to jump into production just as a Vanadium price boom would happen.
