Results from experimental tests designed to characterize differences in the fatigue or creep--fatigue properties of heats of Type-304 stainless steel are reported. These tests included strain controlled fatigue with and without tensile hold times as well as cyclic stress-- strain curve generation at 593 deg C. Although differences in cyclic hardening characteristics were found in four heats of stainless steel tested, little or no difference in cyclic lifetime occurred, with or without tensile hold times, for three of the heats tested. The fourth heat (Ht. No. 8043813) showed an increased resistance to creep-fatigue damage which was tentatively attributed to subtle differences in residual element chemistry. Bilinear constants were also calculated for the four heats and comparisons are made between bilinear and cyclic stress-- strain curves. (3 tables, 7 figures) (auth)
