CPM 4V is very close to the composition of Bohler Uddeholm Vanadis 4 Extra. It has better edge holding than CPM 3V and is tougher than M4.
I think Crucible was brilliant to make this steel. V4E is an excellent steel with one problem. It is very hard to buy from BU. We've been trying to get this steel for years and have only succeeded in getting a few small pieces. Crucible recognized the demand and made CPM 4V. V4E has the advantage of its third generation particle metallurgy. CPM 4V has the advantage of being available for sale.
CPM-3V, CPM-M4, Pyrovan and Vanadis 4 Extra are shown in the table above for comparison purposes.
