Pit growth kinetics of additively manufactured MoNi over-alloyed type 316L stainless steel

Journal of Materials Research and Technology, 2023
The microstructure and corrosion performance of wrought, laser powder bed fusion (LPBF), and MoNi over-alloyed LPBF type 316L stainless steel is compared. Adding Mo and Ni to LPBF 316L stainless steel resulted in ẟ-ferrite.
