2. RE: Relative fatigue strengths of 17-7PH and 15-5PH stainless steel. 17-4 PH and 15-5 PH are actually very close. 15-5PH is the "little brother" of 17-4PH with slightly less chrome and higher Nickel in order to minimize the formation of the delta phase which is detrimental for fatigue.

Abstract. The hot deformation behavior of 15-5 PH stainless steel has been studied using hot compression tests over the temperature range of 900–1150 °C and strain rates varying between 0.001 and 0.5 s −1. The results showed that dynamic recrystallization is the main softening mechanism when the alloy deformed at imposed temperature and ...
of a Nitronic 60 circular spline and 15-5PH H1075 flexible spline was ultimately chosen. It was surprising though, that 15-5PH H1075 on both circular and flexible splines outperformed the heritage material combination (Melonited Flex Spline against a 15-5PH Circular Spline) and also could have been used in the flight build.
