Low alloy steels (LAS) are widely used in the marine and offshore oil and gas industry for various applications from bolting to large pressure containing heavy wall forgings. These materials are subject to various types of corrosion (general or uniform, pitting, crevice, etc.) and degradation in seawater environment. However, their selection for the applications, in comparison with stainless steels and corrosion resistant alloys, is justified due to their availability, manufacturability, proven service history, and lower cost.

Precipitation hardened (PH) Ni-based alloys have been utilized in oil and gas industry for decades. Among them, UNS1 N07718 because of its performance in sour wellbore fluids and in hydrogen charging environments has received the most attention for multiple upstream applications such as tubing hangers, production stab, multi-phase flow meter bodies, valve stems, etc. It has been reported that the alloy performance is generally acceptable for many applications up to 175 °C (350 °F) – 204 °C (400 °F) in the exposed wellbore environments such as sour production fluid, completion brine, and depending on metallurgical processing and microstructure externally exposed to SWCP at the seabed temperature.

Fatigue and Static Crack Growth Rate of Cr-Mn Stainless Steel in Aerated Brine Simulating Drilling Applications

Product Number: 51323-19152-SG

Publication Date: 2023

Directional drilling tools for oil and gas exploration is one industrial application where Manganese (Mn)-stabilized austenitic stainless steels with different amounts of other alloying elements like Chromium (Cr), Nickel (Ni) and Molybdenum (Mo) have found extensive use in spite of the demanding requirements in terms of mechanical properties and corrosion resistance. The limited resistance of this type of austenitic stainless steels to environmentally assisted cracking (EAC) in hot chloride (Cl-)-containing environments is well known. Chloride-bearing environments at elevated temperatures are not uncommon in drilling operations and can indeed challenge the EAC-resistance of CrMn-stainless steels

Fatigue crack growth rate (FGCR) is essential knowledge for the design of high-pressure hydrogen storage vessels, which are subject to repeated pressurization and depressurization cycles. High strength, low alloy steels are widely used for this application. However, these materials are known to be sensitive to hydrogen assisted cracking, meaning their crack growth rate under repeated cycles of pressurization and depressurization is significantly enhanced due to the interaction of hydrogen gas with the metal, compared to an inert environment. This work reviews existing literature on commonly used low alloy, quenched and tempered (Q&T) steels. Additionally, recently generated data on very high strength low alloy grades, as well as low carbon, low alloy, weldable steels are presented in comparison. These results illustrate common trends and similarities for FCGR in hydrogen gas and discuss differences in alloy design and manufacturing process parameters affecting materials performance in the target environment.

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.

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
additively.
