All right, I'm going to put this out there again but I'm not going into longwinded detail again.

AQ17 is the same as 17-4PH (H1150 condition)..............................135,000 PSI tensile, 105,000 tension, 70,000 torsion
AQ22 is Nitronic 50 With a slightly different H/T process..................145,000 PSI tensile, 130,000 tension, 86,000 torsion
K Monel is nickel 500 or K500.............................................. ........145,000 PSI tensile, 110,000 tension

These materials are all subject to work hardening if not machined correctly. They can get micro stress cracks and fail.
