Abstract The effect of chemical composition on the behavior of low alloy steels in a hydrogen sulfide environment was studied with regard to corrosion, hydrogen absorption, and sulfide stress cracking. Results were interpreted in connection with microstructure and carbide precipitation. The addition of chromium results in the promotion of hydrogen absorption presumably due to the precipitation of incoherent carbides, thereby reducing, in general, the resistance to SSC. Fine coherent carbides appear to be beneficial, or at least not detrimental, to SSC resistance; e.g., Mo2C, VC, TiC, and NbC. Microstructure seems to affect both hydrogen absorption and SSC resistance largely through the trapping behavior of hydrogen at the carbide/matrix interface.

AbstractLow-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.
