Type 304 Stainless Steel

The influence of thermal exposure at 800, 1000, and 1200°F (427, 538 and 649°C) on the tensile properties of type 304 stainless steel has been experimentally determined. Specimens were exposed in static sodium for durations of 1000, 3500 and 10,000 hr. Tests were performed at room temperature and the respective exposure temperatures at nominal strain rates from 3 × 10−5 to 10 s−1. Exposure at temperatures to 1000°F (538°C) did not greatly alter the elevated temperature strength, ductility, or strain rate sensitivity of the subject material. At 1200°F (649°C) strength properties were unchanged by exposure at this temperature while ductility was increased at the lowest strain rate and slightly reduced at the higher rates. The room temperature strength was unchanged and ductility slightly reduced after exposure for 10,000 hr at each temperature.

Strength And Ductility

The high strain rate tensile properties of solution annealed Type 304 stainless steel have been determined experimentally. Tests were performed at strain rates ranging from 3 × 10−5 to 1 × 102 in./in./sec at temperatures from 600 to 1600 deg F. At temperatures to 1000 deg F, the strength and ductility are largely insensitive to variations in strain rate, whereas at temperatures from 1200 to 1600 deg F, significant increases in both strength and ductility are observed with increasing strain rate.

Type 304 Stainless Steel

The strain rate sensitivity and short-term relaxation behavior of Type 304 stainless steel were investigated in the uniaxial strain rate jump tests with intermittent periods of relaxation at room temperature and at 650°C. At room temperature material exhibited conventional strain rate sensitivity and no strain rate history effect. The high-temperature experimental results revealed a complex and dramatically different material behavior. At 650°C the pattern of strain rate sensitivity was not set as soon as the plastic flow was fully established, but continued to evolve with the further straining in the plastic range. Test results indicate that at 650°C the material may exhibit a strain rate history effect. Both at room temperature and at 650° C the relaxation behavior was independent of the stress and/or strain level at the beginning of the relaxation, but depended nonlinearly on the strain rate preceding the relaxation test. Prior aging had no significant influence on the rate-dependent material response. The irregular material behavior at 650° C is attributed to dynamic strain aging as indicated by serrated stress-strain curves (the Portevin-LeChatelier effect).

Type 304 Stainless Steel

Four kinds of creep constitutive models, i.e., strain-hardening, modified strain-hardening, kinematic-hardening, and mixed-hardening theory, are evaluated on the basis of creep-test results on type 304 stainless steel at 650°C under repeated multiaxial loading. The predictions of the four models are compared with the experimental results. It is shown that substantial differences appear among these predictions under large rotations of the principal axes of the deviatoric stress tensor, and that none of them can describe with sufficient accuracy the transient increase of strain-rate and the noncollinearity between the deviatoric stress and creep strain-rate vectors which are observed just after the stress-rotations.
