Abstract Scope |
Multiple high hardness steel (HHS) alloys were designed and produced to evaluate the role of composition and processing on the hydrogen embrittlement (HE) susceptibility towards preventing delayed cracking. Four alloys were produced in-house to meet MIL-DTL-46100E and were compared alongside a commercially available steel. HE testing was performed using ASTM E8 specimens, electro-chemically charged with hydrogen in acid. Test results reveal correlation between material structure and properties and hydrogen embrittlement performance. The findings in this study could lead to better understanding of methodologies for reducing HE susceptibility in HHA steels. |
