The effect of tensile hold time on the value of N f of 304 SS at 550 °C [15], [16] and 538 °C [5], [7], [8], [17] can be found in Fig. 4.When the temperature is 550 °C, the tensile hold time on the creep fatigue endurance can be neglected by comparing with the continuous cycling when the hold time is lower than 1.0 min.After hold time of 1.0 min, the number of cycles to .Creep is the slow, time-dependent strain that occurs in a material under a constant strees (or load) at high temperature. High temperature is a relative term, dependent on the materials being .Length of time that the alloy is subjected to a given temperature. Just to name a few potential factors that might affect the performance of a steel alloy being exposed to high temperature applications. For example, say that you had a container made of plain steel that you were passing through a process where the temperature would reach 1,000 . For materials that cannot be expressed in variable-separated form, a combined function called θ projection [31], [32], [33] has been developed for long-term creep as: (4) ε c = θ 1 (1 − e − θ 3 t) + θ 2 (e θ 4 t − 1) where the first term corresponds to rate-decrease effect (such as in primary creep) and the second term corresponds to rate-increase effect (such as in .

This expansion coefficient not only varies between steel grades, it also increases slightly with temperature. Grade 304 has a coefficient of 17.2 x 10-6 /°C over the temperature range 0 to 100°C but increases above this temperature. The effect of thermal expansion is most noticeable where components are restrained, as the expansion results in buckling and bending.Fig. 3.
