Characterization of 316LN stainless steel gas-atomized powders and parts produced by Selective Laser Melting
Abstract
A batch of gas-atomized 316LN stainless steel powder was thoroughly characterized to determine chemical composition, particle size distribution, particles morphology, tap density and flowability. Effect of powder drying was studied on SLM specimens density, tensile properties and impact strength. Drying allowed to increase density from 96.9% to 99.6% and obtain mechanical properties higher than minimal value expected for forged 316LN. Fracture surfaces of tensile bars observed by SEM explained the differences measured in mechanical properties. Properties and energy densities are compared to previously published ones.
