Abstract The SCC susceptibility of sensitized Type 304 stainless steel was studied using slow strain rate tests in 0.01 M NaCl as a function of applied potential at temperatures ranging from 100 to 250 C. Potential-temperature domains in which purely IGSCC, simultaneous IGSCC and TGSCC, and IGSCC accompanied by pitting corrosion have been determined. A critical potential for IGSCC and its dependence upon temperature was measured. This critical potential is equal to the pitting potential at temperatures lower than 150 C, but at higher temperatures, it lies within the passive range of the alloy. Above 150 C, the potential for breakdown of passivity becomes independent of temperature and corresponds to the potential at which TGSCC occurs on sensitized and on quench-annealed material. Interrupted slow strain rate tests were conducted to determine the time at which intergranular cracks start to propagate. On the basis of these data, average intergranular crack propagation rates were calculated. An apparent activation energy of 29 ± 12 KJ/mol was determined in the temperature range 200 to 275 C. It was also found that propagating intergranular cracks can be arrested by changing the potential to a value which is lower than the critical potential.

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.

A model for stress-strain behavior under hot working conditions has been proposed. Based on experimental data, equations for the dependence of flow stress on strain, strain rate, and temperature have been developed. Application to type 304 stainless steel and AISI 1055 steel has been demonstrated.

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.

Abstract The effects of load waveform on intergranular stress corrosion cracking (IGSCC) susceptibility have been examined for sensitized Type 304 stainless steels in a 290 C high purity water loop. Concerning the strain rate in the trapezoidal stress waveform, it was found that IGSCC susceptibility was higher for smaller values of the strain rate. It was also shown that IGSCC susceptibility became higher when the holding time at the upper stress was prolonged, and when the upper stress was high. The occurrence of IGSCC for sensitized Type 304 stainless steel became easy due to the application of cyclic tensile stress in 290 C high purity water.
