I do get the need for a material that is corrosion resistant, could some kind of nitride or iridite 14-2 or nickel plating could be used, maybe, if the NEW material was carbon steel and NOT stainless???
I have thought the same thing. Not to mention off road torsion bars being cycled like crazy, in 2 directions. 300M seems to be the material of choice for shafts that are subjected to heavy cycling.
With the rudder, turn fins and props all made of carbon steel, I don't really see the "requirement" for a corrosion resistant material, specially on something that cycles thru a prop shaft as fast as a TFH.

I don't think I would want to run a carbon steel shaft on the GN, but it would not surprise me one bit if the stuff Wayne is referring to is a carbon steel.
