Purpose is to show how the short-term elevated-temperature ultimate tensile strengths (UTS) can be used as a possible index for estimating short- and perhaps long-term creep-rupture strength for several austenitic stainless steels. Creep-rupture strength data were collected on elevated-temperature mechanical properties of types 304 and 316 stainless steel. The data collection was limited to sources that provided both short-term tensile and creep-rupture results with two exceptions. Data points are also used for types 201, 202, 303, 304, 304L, 304H, 316, 316L, 316H, 316N, 321, 321H, 347, and 347L. 10$sup 3$, 10$sup 4$, and 10$sup 5$h creep-rupture strengths are plotted as a function of UTS and used to fit the equation for creep rupture strength: S = $alpha$ exp $beta$(UTS). The constants $alpha$ and $beta$ are tabulated for several stainless steels. (DLC)
