“…In addition, Ni is the only important element to improve the stress corrosion resistance of austenitic stainless steel [38,39]. The standard API RP 571 also proposes that the Ni content of the alloy material is the most sensitive to chloride SCC at 8~12% [15], while the chemical composition analysis of the pipeline has a Ni content of about 9.9%, which is in the sensitive range of chloride SCC.…”

This paper presents the failure analysis of the crack and leakage accident of a crude oil pipeline under CO2-steam flooding in the western oilfield of China. To analyze the failure behavior and cause, different testing, including nondestructive testing, chemical composition analysis, tensile property testing, metallographic analysis, and microanalysis of fracture and chloride stress corrosion cracking (SCC) testing, are applied in the present study. The obtained results showed that the pipeline under the insulation layer of high humidity, high oxygen content, and high Cl− environment occurred pit corrosion, and the stress concentration area at the bottom of the corrosion pit sprouted cracks. Besides, it is demonstrated that the cracks were much branched, mostly through the crystal, and the fracture showed brittle, which is consistent with the typical characteristics of chloride SCC. Meanwhile, the insufficient Ni content of the pipeline material promoted the process of chloride SCC, and the high-temperature working conditions also aggravated the rate of chloride SCC. In addition, efficient precautions were provided to avoid fracture.

“…It is found that Sn segregation reduces the grain boundary cohesion, and Nb segregation enhances the grain boundary cohesion; that is, reducing Sn or adding Nb can improve the corrosion resistance of Zr alloy. Yazdanpanah et al [ 20 ] studied the effect of Cr content on corrosion resistance by the microcapillary method and found that samples with lower Cr content within the standard limit had significantly lower resistance to localized corrosion. Pham et al [ 21 ] used first‐principles calculations to study the behavior of Fe grain boundaries under the action of residues such as S, P, N, C, and B to illustrate the effect of stress corrosion and its mechanism.…”

Segregation of interface elements is the main factor affecting the corrosion activity of microareas around Al2O3 inclusions rather than galvanic corrosion. In this work, the effects of segregation of Cu, V, Ni, Mo, B, and P elements on the interfacial bonding strength and microareas corrosion activity around Al2O3 inclusions are analyzed in detail using 3D atomic probe and first‐principles calculations. In the results, it is shown that Cu, V, Mo, B, and P elements reduce the stability of the α‐Fe/Al2O3 interface. In addition, the segregation of Cu, V, Mo, B, and P elements at the interface also enhances the adsorption capacity of Cl and ultimately improves the microarea corrosion activity around Al2O3 inclusions. Ni element can enhance the stability of α‐Fe/Al2O3 interface, and the segregation of Ni element at the interface weakens the adsorption capacity of Cl and ultimately reduces the microarea corrosion activity around Al2O3 inclusions.

“…[ 4 ] Yazdanpanah et al reported that the high chloride concentration resulted in high susceptibility to pitting and stress corrosion cracking (SCC) for 304 SS specimens. [ 5 ] As another environmental factor for corrosion, temperature has also been studied because of its effect on the corrosion of SS. Xuan et al reported that the corrosion resistance of 304 SS decreased with the increase of solution temperature in simulated cathode environment.…”

In this paper, the passive behavior of 304 stainless steel (SS) in NaCl solution is studied by electrochemical methods and surface analysis. The polarization measurement results show that the pitting potential (Ep) has a simple linear relationship with the temperature increase. Scanning Kelvin probe results show that the surface potential difference on the surface of 304 SS is well correlated with the temperature. Scanning electron microscope results show that the rupture of the passive film accelerates with the increase of temperature. The X‐ray photoelectron spectroscopy analysis shows that the high temperature causes more oxidation on the surface of 304 SS, leading more Cr3+ oxidized to Cr6+ at high temperature.
