Investigation of hydrogen embrittlement prevention effect on electropolished 316 L austenitic stainless steel

초록

This study investigated the surface properties of 316 L austenitic stainless steel in a hydrogen environment before and after electropolishing. The impact of electropolishing on hydrogen embrittlement resistance was evaluated, and hydrogen desorption in the material was analyzed based on surface conditions. Results demonstrated that changes in chromium content on the electropolished surface affected hydrogen embrittlement susceptibility, confirming the suitability of this treatment for material improvement in hydrogen environments. © 2025
