Deformation-induced martensites in metastable austenite stainless steels affect their physical and chemical properties. Electrochemically induced annealing (EIA) is a recently discovered phenomenon. Although the reason why EIA treatment causes martensite to decrease or disappear is not clear, the effect of the martensite decrease or disappearance is supposed to be the same as that caused by heat-treatment annealing. The pitting resistance of the EIA-treated samples is compared with that of the untreated ones, through open-circuit potential, metallurgical microscope observation, and potentiodynamic scanning. The following results are obtained for the EIA-treated samples, after a 1.5-V anode charge in a 3.5 pct NaCl solution, as compared with the untreated samples: the deepest pit in the treated samples is far more shallow than the deepest pit in the untreated samples; there is far less pitting in the treated samples than in the untreated samples; and the largest pit in the treated samples is much smaller than the largest pit in the untreated samples. Initially, the open-circuit potential of the EIA-treated sample was 64 mV higher than that of the untreated one, but they reach close values after certain period of time. The pitting breakthrough potential, E b , of the EIA-treated sample is about 0.2 V higher than that of the untreated one. Therefore, EIA is a method that has the potential to promote the pitting resistance of metastable austenite stainless steels.

“…In this study, the Ni/Cr ratio of 304 austenitic stainless steel was about 0.44. Zhang et al [31] found that during the annealing process of austenitic stainless steel, some austenite structures that are reversely transformed with the shear mechanism will retransform into martensite during cooling. Meanwhile, the stacking fault energy (SFE) is closely related to the formation of martensite in austenitic steel wire during cold drawing [32].…”

Plastic deformation at room temperature, and the proceeding heat treatments, are important processes for optimizing the microstructure and mechanical properties of austenitic stainless steel. The microstructure and mechanical properties of cold-drawn 304 austenitic stainless steel wire were investigated after annealing at 700 and 800 °C, with different times (20, 40 and 60 min) and drawing strain (0.4, 1.0 and 1.5). Electron backscattered diffraction (EBSD) techniques, trans-mission electron microscope (TEM) analysis, differential scanning calorimeter (DSC) and tensile tests were performed in order to study the microstructure evolution and mechanical properties during different annealing processes for the 304 austenitic stainless steel wire. The results showed that the quantity of α’ martensite and dislocations increased with an increase in the strain, which means that, while the ultimate tensile strength of the cold-drawn wires elevated, the elongation reduced. The mechanical properties of stainless steel wires also varied with the evolution of martensite transformation characteristics, density of stacking fault, dislocation and twin, as well as the recrystallization degree under various annealing conditions. The recrystalli-zation temperature of steel wire was mainly determined by the magnitude of the strain, while the martensite reversal temperature was determined by the stacking fault energy and the de-formation value. The temperature of recrystallization and martensite reverse in steel wire de-creased with the increment of the strain. The balance of tensile strength and elongation of steel wire can be obtained by adopting the proper annealing process combined with cold-drawing deformation. In this paper, we showed that a good combination of strength and elongation in 304 austenitic stainless steel can be obtained with a strain of 1.5 annealed at 800 °C for 20 min.
