Creep-rupture data are presented for a reference heat (heat 9T2796) of Type 304 stainless steel. Temperatures range from 482 to 871°C (900 to 1600°F), and times range from 0.0036 to 50 Ms (1 to 15,000 h). The data include rupture life, tertiary creep, true rupture strain, and true tertiary creep strain. Correlations are developed for rupture life vs engineering stress, modulus-compensated true stress, and modulus-compensated effective stress. The temperature dependence of the correlations is also examined. The tertiary creep is correlated with the rupture life. The rupture strain is correlated with both the modulus-compensated true stress and the modulus-compensated effective stress. Finally, the true tertiary creep strain is correlated with the rupture strain.
