The TI coating is only supposed to make the surface more durable, but I believe Tamiya makes them out of harder steel as well, or the process of coating them with TI makes the underlying steel harder. I bent all of my "stock" shafts in succession. I have never had a TI shaft bend, but I have broken a couple (fractured) in front-end collisions. The fact they snap, but don't bend lead me to believe they are harder steel.
All in all, I feel the TI shafts are way more durable and are supposed to make your O-Rings last longer.
