Unexpected brittle failures of UNS NO5500 drill string parts and non-magnetic drill collars have recently been observed in cases where the UNS NO5500 components were galvanically coupled to carbon steel in concentrated salt solutions at temperatures between ambient and higher than 373 K. Cracking occured preferable at locations with a tri-axial stress condition (roots of threads) and has been ascribed to hydrogen embrittlement.

Hydrogen gas is called to play a key role in the energy transition and initiatives needed for a
decarbonization of the economy. Initially, assets for energy storage and transport were developed and qualified for the purpose of the oil and gas industry, especially natural gas. Repurposing of existing assets for the use of hydrogen gas, or creation of new dedicated hydrogen transport and storage infrastructure, is a great challenge for future hydrogen projects. It includes the qualification of steel materials under
hydrogen gas environment.

A decarbonized energy system is underway worldwide. The Paris Agreement goal is to keep global warming “below 2 degrees Celsius above preindustrial levels, and to pursue effort to limit the temperature increase even further to 1.5 degrees Celsius.” To achieve this long-term temperature goal, big changes are needed in the ways energy is produced, distributed and storage.

Introducing hydrogen into the existing natural gas pipeline network has been proposed as a way of decreasing greenhouse gas (GHG) effects from the combustion of natural gas. However, hydrogen is known to degrade the strength of many alloys through hydrogen embrittlement (HE). Therefore, it is important to carefully define the maximum allowable pressure hydrogen concentration for each alloy to avoid detrimental effects to the material. In this study, hydrogen testing was carried out to evaluate the susceptibility of selected alloys to hydrogen embrittlement via controlled exposure to methane gas blended with different hydrogen concentrations and at different pressures. In addition, a diffusible hydrogen test was carried out to identify the amount of solid solution hydrogen in the samples. The alloys were representative of common regulator materials used in gas pipeline products. Tensile samples with a highly polished surface were tested under five different environments: 1.6 MPa (16 bar) of 10% and 50% hydrogen gas mixture, and 10 MPa (100 bar) of 10%, 30%, and 50% hydrogen gas mixture after soaking between 2 days and 5 weeks. Tests on control samples were performed in ambient environment. The results from this study provide insight into the effects of hydrogen on various alloys under five different environments and indicate which alloys performed best under a given environment.

Hydrogen emerged as a solution to increasing environmental problems and is becoming an important energy resource. However, hydrogen can deteriorate the mechanical performance of metallic components. This phenomenon is known as hydrogen embrittlement (HE). Engineering steels, such as nickel-chromium-molybdenum steels, are widely used in the industry and can be attractive materials for hydrogen applications such as pressure vessels, owing to a good combination of tensile strength (up to 1.1 GPa) and ductility (e.g., 10 % or higher). They can decrease product weight and reduce construction costs. However, as HE susceptibility tends to increase with increasing strength of steels, high-strength steels are susceptible to HE when used in hydrogen gas environment. The aim of this paper is to investigate the susceptibility of different engineering steels to hydrogen embrittlement. Three martensitic Cr-Ni-Mo steels were investigated. Slow strain rate tests were performed in gaseous hydrogen at 100 bar (10 MPa) and room temperature. Microstructure characterization and fractography study were carried out. Ni-Cr-Mo steels show a martensitic microstructure with precipitates in quenched and tempered condition. Their YS and UTS are higher than 1000 MPa (145 ksi) and 1100 MPa (159 ksi), respectively. Hydrogen gas degrades the ductility of Cr-Ni-Mo steels considerably, while strength deteriorates slightly. Fractography is characterized by a brittle fracture assisted by hydrogen. Hydrogen-Enhanced Localized Plasticity (HELP) is seen to be the primary failure mechanism in martensitic steels.

Electroplating is a coating technique used to apply a metallic deposit to alter the properties of the substrate surface. Traditional electroplating involves submerging a part into a tank of electrolyte plating solution and passing a current between the part and an anode, any area that should not be plated must be masked off. Brush electroplating is a portable method of electroplating localized areas without the use of an immersion tank.

Precipitation hardenable nickel alloys N09925, N07718, N09945, N09946 and N07725 provide high strength and excellent sour service corrosion resistance for critical downhole oilfield applications. This family of alloys achieves yield strength minimums ranging from 120 to 160 KSI (827-1103 MPa) and can withstand high temperatures and partial pressures of H2S. The primary strengthening mechanism is the formation of γ’ and γ” nanometer sized particles during an age hardening heat treatment.

Parts produced via additive manufacturing (AM) are being adopted broadly among many industries and
used in an array of applications. AM parts are attractive to these industries for several reasons. Complex
geometries that cannot be manufactured using traditional, subtractive methods can be produced

As long ago as 1973, design codes1 considered the possibility of hydrogen embrittlement due to CP. Between 1986 and 1995^2-4 the failure of DSS fasteners subjected to CP were reported. These were associated with high ferrite levels in the steel (approximately 70%) combined with precipitation hardening at 475°C to give the high levels of strength desired for fastener applications. At the same time, the susceptibility of DSS welds to hydrogen embrittlement had been reported5. Just like the fastener failures, the hydrogen cracking of welds was associated with high ferrite levels (70%), highly restrained joints and in the case of welds, high levels of diffusible hydrogen.
