Commercial stainless steel 316L (316SS) has been used in the industry due to its mechanical properties, corrosion, and abrasion resistance. The additive manufacturing (AM) route has been used to improve these properties. Among the methods used in AM, we can find the ball milling method as a solid synthesis route where different variables directly impact the nanostructure of the synthesized 316SS. We studied the effect of the milling processing parameters in the microstructure, and the electrochemical properties due to different synthesized conditions, such as 300 and 350 rpm and different times, 20 and 40h with a ball per ratio [6:1]. The processed samples via ball milling were compared to the AM selective laser melting and commercial 316SS samples; the processing parameters and route were characterized via electrochemical methods. Two of the synthesized samples, 300 rpm 40h and 350 rpm 20h, presented lower current density and therefore influencing the corrosion resistance property.
