Fatigue behavior and life prediction of stainless steels after hydrogen charging

Key Points

• Fatigue behavior reveals significant changes under hydrogen charging conditions, impacting lifespan.
• Key evidence indicates an increase in crack propagation rates and overall brittleness when hydrogen is present.
• Observation involved mechanical testing following hydrogen charging to assess failure at various stress levels.
• These findings highlight the need for improved material assessments in hydrogen environments to ensure structural safety.
