Abstract. Ferritic stainless steels are a cost efficient and more climate-friendly alternative to austenitic grades for high temperature applications because of their lower Ni-content. These grades usually show some time dependent thermal softening mechanisms at temperatures over 800 °C. The tendency to show high temperature creep behavior of three ferritic stainless steel grades is analyzed with high temperature tensile tests and modified creep tests. The results show that the reference grade 1.4509 does show this behavior, while the two grades with slightly higher contents of chromium and additional elements such as molybdenum, titanium and copper experience less high temperature creep at similar loadings. While both grades also show extensive softening at temperatures above 850 °C, the overall strength level is always higher than for the reference grade.
