“…Consequently, the more reverted austenite in the over-aged specimen the less susceptible to hydrogen embrittlement would be the result. Alternatively, the accumulation of hydrogen at the interfaces between matrix and inclusions led to interfacial separations, resulting in an increased susceptibility of the alloy [23][24][25].…”

“…H 2 S coverage can be affected by environmental NaCl concentration, H 2 S activity and pH. According to the study of Cancio et al [20,21], at constant brine ionic strength and pH, H 2 S coverage on steel surface is controlled by H 2 S fugacity or H 2 S activity. Zhang et al evaluate the effect of Cl − accumulation on H 2 S corrosion, the results show that Cl − has small radius and strong penetration, can penetrate corrosion scales and be adsorbed on the metal surface [22].…”

The sulphide stress cracking of high strength low alloy (HSLA) carbon steel C110 is related to the hydrogen absorption process. The objective of this research is to evaluate the effect of adsorbed H 2 S and Cl − on hydrogen permeation in C110, by studying the responses of hydrogen permeation current and characteristic inductance under environment with different H 2 S activities and NaCl concentrations using electrochemical methods, including hydrogen permeation method and electrochemical impedance spectroscopy (EIS). The hydrogen permeation current measured in Devanathan-Stachurski cell suggests that the enhance effect of the adsorbed H 2 S on the hydrogen absorption follows an adsorption isotherm behaviour as a function of H 2 S activity in solution. The inductive response of EIS under different H 2 S activities shows consistency with hydrogen permeation results. The EIS results also indicate that the coverage of H 2 S was suppressed by Cl − . A good correlation about the effect of adsorbed Cl − is found between inductive response and hydrogen permeation current.

“…As a result, nickel is expected to increase SSC resistance (Pressouyre, 1979). In contrast, other irreversible traps, such as MnS and oxide interphases, are undesirable because they can act as potential flaws themselves (Chavane et al, 1986). Stringent maximum sulfur content limits and strict control of shape and distribution of inclusions is paramount for maximum SSC resistance (EFC, 2009;Kimura et al, 1989;NACE-ISO, 2001), e.g., API 6A Table 10 and API 5CT Tables C.5 (API, 2004(API, , 2010.…”

“…Given that nickel decreases the A c1 temperature of the steel and refines microstructure, nickel additions to LAS are expected to increase HE resistance (Chavane, Habashi, Pressouyre, & Galland, 1986). The grain boundary area per unit volume and the number of carbides per unit volume both increase when the microstructure, i.e., both grain and carbide size, are refined.…”

Sulfide stress cracking of nickel-containing low-alloy steels

et al. 2014

Low-alloy steels (LAS) are extensively used in oil and gas (O&G) production due to their good mechanical properties and low cost. Even though nickel improves mechanical properties and hardenability with low penalty on weldability, which is critical for large subsea components, nickel content cannot exceed 1-wt% when used in sour service applications. The ISO 15156-2 standard limits the nickel content in LAS on the assumption that nickel concentrations above 1-wt% negatively impact sulfide stress cracking (SSC) resistance. This restriction excludes a significant number of high-strength and high-toughness alloys, such as Ni-Cr-Mo (e.g., UNS G43200 and G43400), Ni-Mo (e.g., UNS G46200), and Ni-Cr-Mo-V grades, from sour service applications and can be used only if successfully qualified. However, the standard is based on controversial research conducted more than 40 years ago. Since then, researchers have suggested that it is the microstructure that determines SSC resistance, regardless of Ni content. This review summarizes the advantages and disadvantages of nickel-containing LAS in terms of strength, weldability, hardenability, potential weight savings, and cost reduction. Likewise, the state of knowledge on the effect of nickel on hydrogen absorption as well as SSC initiation and propagation kinetics is critically reviewed.
