CPM T440V....AKA 6V, AKA S60V...hasn't been made for several years.
The best way to (maybe) find some would be to contact some of
the old Crucible distributors and inquire about old stock...
Added: Flagg Steel,in STL used to be a Crucible Distributor. If
they're still around,try them.They may be able to point you in a better
direction.
Also, Admiral Steel ,in Alsip,Il.used to sell 440V....
