Interest in hydrogen is rapidly growing due to rising greenhouse gas emissions and the depletion of fossil fuel reserves. Additive manufacturing (AM) extensively employed produce high-quality components, with a strong focus on enhancing mechanical properties. The efficiency cost-effectiveness AM have further increased interest its application components capable withstanding demanding conditions, such as those encountered technology. In this study, 316L stainless steel specimens were fabricated using via selective laser melting (SLM) technique. then underwent various post-processing heat treatments (PPHT). A subset these specimens, measuring 50 × 3 mm3, was tested electrodes water electrolysis cell for oxyhydrogen (HHO) production. HHO flow rate electrolyzer evaluated at 60 °C under varying currents. remaining their susceptibility embrittlement storage including testing both room cryogenic temperatures. Tensile Charpy impact before after charging. fracture surfaces analyzed scanning electron microscopy (SEM) assess influence characteristics. Additionally, as-rolled stainless-steel examined comparison PPHT steel. primary objective study determine most efficient alloy processing condition optimal performance each application. Results indicate that exhibits superior production material vessels, demonstrating high resistance embrittlement.
