“…SCC of non-sensitized steels have been also reported in the thiosulfate solutions containing chloride ions10,95,96,[100][101][102]114 . Stainless steel Type 304L was reported to suffer SCC in the 4M chloride solution containing from 10 -3 M to 10 -1 M S 2 O 3 2at 353 K and crack27propagation was found to increase slightly with increasing concentration of S…”

“…sulfur oxyanions) have been reported to cause SCC failures of steels in variety of applications24,[92][93][94][95][96][97][98] , including in the nuclear, pulp & paper, and petroleum industries. SCC of stainless steels is generally initiated by the destruction of the passive film followed by the growth of a pit to a critical dimension at which a crack will nucleate.…”

Thiosulfate salts have been known to be dangerous corrosion promoters for over 30 years, when present under typical service conditions. This paper reviews the role of thiosulfate anion in causing localized corrosion and/or stress corrosion cracking of steels. Electrochemical and mechanical aspects associated with the pitting and stress corrosion cracking of steels in thiosulfate-containing environments are thoroughly discussed and reviewed. In particular, results

“…The triglyceride characterization by IR spectroscopy of palm oil, Figure 2, shows a very strong signal at 1743 cm −1 for the C = O stretching ester vibration. This signal is shifted to lower frequency at 1642 cm −1 for the fatty amides (33). For gemini surfactant, this signal is shown at 1720 cm −1 corresponding to the ester group.…”

“…However, due to problems rising with the toxicity, flammability and corrosiveness of H 2 S gas, several authors have suggested as alternative sour gas simulating solution the use of 5.0 wt. % NaCl + 2.5% Acetic acid + 10 −6 M sodium thiosulphate (Na 2 S 2 O 3 ) solution in distilled water (33)(34)(35)(36)(37). A completely sealed glass cell was used for the experiments.…”

A no-ionic gemini surfactant, namely bis(2-((2-palmitoamidoetil) amino) etil) 1H-imidazol-4,5dicarboxilate, was synthesized from the fatty acids contained in the palm oil and evaluated as corrosion inhibitor for UNS S41425 type supermartensitic stainless steel in presence of H 2 S. Used techniques involved potentiodynamic polarization curves, linear polarization resistance and electrochemical impedance measurements. Additionally, the obtained inhibitor was characterized by Infrared and 1H, 13C RMN spectroscopy. Results have shown that the corrosion rate of the steel was markedly decreased by the addition of the imidazole-type of inhibitor, reaching its maximum efficiency at certain inhibitor concentration, decreasing with a further increase in its concentration. This decrease in the corrosion rate was due to the physical adsorption of the inhibitor on to the steel surface following a Langmuir type of adsorption isotherm, affecting both anodic and cathodic reactions.

“…The SCC susceptibility was evaluated by the ratio (R) between the percentage strain to fracture (ε f %) in the test solution and that in air (for 25 • C tests) or water (for 80 • C tests). R values equal to or higher than 0.8 were considered an index of immunity to SCC [36].…”

The stress-corrosion cracking (SCC) behaviour of two lean-duplex stainless steels (DSS 2304 and LDSS 2404) was studied by slow strain-rate tests (SSRT) in 20% NaCl solution at 80 • C (pH about 6) and in NACE TM-0177 solution at 25 • C (pH 2.7), both in the absence and in the presence of thiosulphate ions (S 2 O 3 2−). The SCC susceptibility of the two alloys was compared to that of LDSS 2101 investigated in a previous study. LDSS 2404 was always immune to SCC, while DSS 2304 (and LDSS 2101) suffered this corrosion form at specific concentrations. The high SCC resistance of DSS 2404 in both environments was connected to its high Mo content, while the significant SCC susceptibility of LDSS 2101 in NACE TM-0177 solution was likely due to the high Mn content of the alloy.
