All data are for solution-annealed plate or bar except where indicated.
While comparing stress to cause rupture and stress to cause 1 percent creep for a given amount of hours can demonstrate a relative ranking for materials considered, an alternative perspective can be gained by examining the data presented in the above table. Comparative creep curves for various alloys are displayed below. The difference in life between stronger and weaker alloys when tested at the same temperature and stress can be as much as several orders of magnitude. This difference may sometimes be a consequence of seemingly small differences in the stress to produce failure or a finite level of creep in the same amount of hours, as shown in the previous tables above.
