Austenitic stainless steel of type 316L is widely used in industrial hydrogen applications due to its advantageous material properties. The interaction between these material characteristics and hydrogen has been intensively studied for decades. Alongside, additive manufacturing enables new degrees of design freedom as well as the tailored control of material properties. In this work, laser-based powder bed fusion of metals (PBF-LB/M) is used in combination with several post-processes and heat treatments to manufacture 316L specimens with different application related surface and microstructures. After surface analysis, gaseous hydrogen charging in an autoclave at 300 °C and 100 MPa was conducted. Subsequently, the hydrogen uptake was measured via inert gas fusion. The investigation show that the microstructure has a more significant influence on hydrogen uptake than the surface quality. By optimizing the material properties of additively manufactured 316L through beam shaping and heat treatment, the hydrogen uptake was significantly reduced compared to conventionally cold-drawn 316L.
