%X This study delves into the challenge of hydrogen embrittlement in high-strength industries operating in hydrogen-rich environments. It investigates the response of high-strength steel 42CrMo4 to hydrogen loading using fatigue testing and diverse electrochemical conditions. Mechanical properties were analyzed through slow strain rate tests. The uncharged test-1 specimen exhibited robust mechanical attributes and a martensitic microstructure. However, heightened current density in tests-2 and 3 led to hydrogen-induced embrittlement, causing reduced tensile strength, hardness, and elongation, accompanied by brittle fractures. The research advances comprehension of how current density impacts 42CrMo4¡¯s mechanical traits under hydrogen exposure. Insights are applicable to theory and practice, aiding the development of hydrogen-resistant materials for enhanced industry durability. Amid evolving challenges, this study¡¯s insights support the creation of safer, more dependable structures in hydrogen-rich environments.
