What is it about?
The work analyses the pitting behaviour of 316L stainless steels produced by selective laser melting (SLM). The (SLM) fabrication parameters, as well as the post-production characteristics (porosity, microstructure, etc.), were compared to the corrosion performance of the investigated alloys.

Why is it important?
The corrosion of additively manufactured alloys is not yet well understood. Therefore, this work aims to investigate the performance of these recently additively manufactured stainless steels in saline corrosive environments and compare the results with the performance of their wrought counterparts under the same experimental conditions.
Perspectives
The selective laser melted 316L stainless steels showed promising corrosion resistance in comparison to their wrought counterparts. Those results point to the opportunity to widen up the areas in which additive manufactured stainless steels can be applied.
