An experimental program to characterize the creep-crack-growth behavior of 304 stainless steel at several temperatures was conducted. Crack growth rates, da/dt, obtained from center crack tension and compact type specimens were correlated by the energy rate line integral, C*. Experimental data indicate that minor differences in chemistry and microstructure do not significantly influence da/dt versus C* relationship. Also, in the range of 538 to 705°C (1000 to 1300°F), the da/dt versus C* relationship is not significantly affected by temperature. Simple analytical methods of estimating C* are also evaluated.
