| Abstract Scope |
The demand for high strength steels has increased across many industries including automotive, defense, and oil and gas transportation sectors, as these steels can offer numerous benefits in terms of mechanical performance, cost reduction, and sustainability. However, advancements in high strength steels led to concern about the potential risk of hydrogen-related damages, such as hydrogen/H2S cracking and delayed fracture, in their use in hydrogen-rich or hydrogen-producing corrosive environments because hydrogen embrittlement sensitivity of a steel often increases with increasing strength. This presentation explores strategies to enhance hydrogen embrittlement resistance in various high strength steel microstructures, including martensitic and austenitic microstructures, through processing and metallurgical design. Key research opportunities are identified to guide the development of steels for safe and effective use in hydrogen-rich environments. |
