Cover Story: This study investigates how build orientation and harsh environments jointly influence the mechanical reliability of L PBF 316L stainless steel. Specimens built in vertical, edge, and flat orientations were exposed for 360 hours to sulfuric acid, sodium chloride, and high-temperature oxidation at 800 °C. Results revealed strong anisotropy—edge and flat samples exhibited higher tensile and yield strength, while vertical samples showed greater ductility. Aqueous environments caused surface degradation and moderate strength loss, most pronounced in vertical builds. High-temperature oxidation triggered σ phase precipitation, increasing tensile strength but reducing yield strength and ductility. Overall, orientation and service conditions critically affect long-term performance. View this paper
