I think I'm missing one, I forget atm.
In anycase I would trust these guys with the ht of vanax and the other high nitrogen steels. Chad Kelly actually got some of the first vanax superclean from Bohler and developed and tested the heat treatment necessary for the best edge retention he could get. He went through a few recipes and tested alot of cardboard. He's shared the recipe with a few others iirc. it requires triple cryo tempers.
There are older variations of vanax with slightly different chemistries to them. Vanax 35,37 and 75. They now only have vanax superclean and have phased those previous versions out.
