The behavior of the steel in the as-built state was compared to that ground up to 2500 grade. Three different aggressive environments were used: 3.5 wt% NaCl water solution, 3 wt% H2SO4 solution, and hightemperature oxidation at 800 ºC. The ground specimens showed higher corrosion resistance. The corrosion resistance was much smaller in the as-built samples for electrochemical tests, and the lowest mass gain after hightemperature oxidation was found in the ground specimens.engAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/316 L stainless steelAdditive manufacturingLaser powder bed fusionSurface roughnessCorrosionOxidationinfo:eu-repo/semantics/article10.1016/j.corsci.2022.110550info:eu-repo/semantics/openAccess
