Not sure what is used for Ti valves, but I do believe that  this is it for
con rods, valve spring retainers, etc.

Their extreme impact strength at high hardness (and strength) levels is
reason why I am puzzled that more use of maraging steels is not
made---after all, they are pretty universal in applications like main rotor
shafts on helicopters--so I guess we think alike!!
