#### ASME B31.3 Design Criteria For Thermal Stress | Calgary, AB

Assuming a typical SA of 345 MPa (50 ksi) (1.25 Sc + 1.255h), and considering that the Code flexibility analysis equations calculate about one-half of the actual peak stress, we find an "endurance limit" f factor of 0.15 (at about 10 cycles). The "endurance limit" f factor for stainless steel would be higher, if calculated by the same procedure.
