Ejector pins are nitride hardened to 65-74 Rc, while the core hardness remains ~35-40 Rc. This allows for zero memory until yield, at which point the inner (softer) portion will allow for bending to occur. However the outer (hardened) portion will split/tear. I did bend one one time (0.25") and split the outer "skin". The impact was tremendous, actually the same rod survived a similar event without any sign of damage on another aircraft. They are superior to anything out there including carbon or Titanium volume-wise
The expectation that this will save an aircraft is stretching it a bit, as the amount of energy required from initial split to fully broken is relatively small. THe advantage I see with hardening is being able to spec a smaller metalic rod to perform the same work as a larger/heavier rod.
