The cross section area was 16 mm2, so to generate 650 MPa stress, I applied 10400 N force but it resulted in 750 MPa stress, so I reduced the force applied to 9400 N which resulted in equivalent stress of 652 MPa.  



But the equivalent alternating stress under fatigue is around 1120 MPa, but as you said isn't this supposed to be 325 MPa?  Also there is an warning as shown below.
