Type 304 Stainless Steel

A recently suggested procedure for estimating the life of a material subjected to fatigue-creep loading is applied to analyze the behavior of Type 304 stainless steel on the basis of the experimental data already available in the literature. The predictive technique is based on a combination of the two separate damage functions for fatigue and for creep. The effect of the tension hold time in interspersed creep-fatigue loading on the material life is taken into account by considering the relaxation stress characteristics during the hold period. The technique also permits the evaluation of damage (or healing) due to a compression hold time. The correlation between predictions and available experimental results obtained on Type 304 SS from 538 to 649° C under various loading conditions is discussed.

Type 304

Available creep and creep-fatigue data on type 304 stainless steel are re-examined in the light of recently generated basic cavitation data on the same material. This basic study has shown creep damage to be a highly inhomogeneous phenomenon, both in space and in time. A small fraction of boundaries are so intensely cavitated by about 10–25 percent of life that for all practical purposes they can be considered cracked. Other similar boundaries, that are similarly oriented with respect to the tensile stress direction, however, are almost devoid of cavities at the end of life. The early nucleation of cracks by creep mechanism has a significant influence on creep-fatigue interactions, particularly for tests at low strain ranges. A simple ductility exhaustion model appears to be able to account for the early crack initiation. A hardness-modified ductility approach appears to provide an upper bound to the ductility displayed by all tests and correlates data for long hold-time fatigue tests at low strain range. Tests at higher strain ranges and/or shorter hold times do not achieve their full potential ductility because their lives are cut short by crack propagation. Their lives can be predicted empirically by an enhanced fatigue crack growth equation in the presence of cavitation damage.
