The microstructure and properties of the additively manufactured alloys are influenced by the feedstock powder. In this research, 316L stainless steel test coupons have been produced using 316L stainless feedstock procured from multiple sources as well as modified using ball milling with additives. The role of the feedstock on the microstructure was investigated using a scanning electron microscope, X-ray diffraction, and transmission electron microscope. Corrosion behavior was studied using cyclic potentiodynamic polarization tests and constant immersion tests. The microstructure and corrosion of the test coupons were dependent on the characteristics of the feedstock.
