I did see actual tabular values for Nitronic 60 based on a brochure that I obtained some time ago (High Performance Alloys, Inc.)
The tabular values were;
Annealed Bar, 1" dia, 37.5 Ksi fatigue limit for 108 cycles
Cold Worked 54.6%, 0.70" dia, 72.5 Ksi for similar cycles
(Fatigue testing on an RR Moore machine).
