“…After this report many researchers [2][3][4][5][6][7][8] dealt with the SCC in these solutions, and they 5,7) reported that the SCC occurs in a particular concentration range of NaCl and in the other range general corrosion occurs or cracking is suppressed.…”

A stress corrosion cracking (SCC) test was carried out at room temperature in aqueous solutions containing both H 2 SO 4 (0-5.5 kmolÁm À3 ) and NaCl (0-4.5 kmolÁm À3 ), in order to study the influences of both solutes on the corrosion type of SUS304 steel. The two solutes have synergistic influence on the corrosion type, that is, SCC and general corrosion occur within a specific concentration range and elsewhere, respectively. For a constant H 2 SO 4 concentration the mass loss of corrosion shows a V-shape when it is plotted against NaCl concentration. On the other hand, maximum crack length of the SCC increases with increasing NaCl concentration up to a certain value, and then decreases. This gives a nearly inverse V-shape curve. In addition, the NaCl concentration ranges for the minimum mass loss and for the maximum crack length are almost the same. It was also confirmed that NaCl concentrations showing the minimum mass loss and the maximum crack length are inversely proportional to H 2 SO 4 concentrations.

An SCC test was carried out in aqueous solutions containing both H 2 SO 4 (0～5.5 kmol/m 3 ) and NaCl(0～4.5 kmol/m 3 ) as solutes, in order to study the influence of the environment on the corrosion type of an SUS304 steel. The both solutes of H 2 SO 4 and NaCl have synergistic influence on the corrosion type, and SCC occurs within a specific concentration region and general corrosion occurs at the other concentrations. For a constant H 2 SO 4 concentration the corrosion mass loss decreases with increasing NaCl concentration up to a certain value and then increases. This tendency makes a V shape curve when the mass loss is plotted against the NaCl concentration. On the other hand, SCC crack length increases with increasing NaCl concentration up to a certain value, passes a maximum, and then decreases. This tendency is just like an inverse V shape curve. In addition, the NaCl concentration ranges for the minimum mass loss and maximum crack length are almost equal. It was also confirmed that these NaCl concentration regions are inversely proportional to the H 2 SO 4 concentration.
