Grade 316L is one of the most versatile austenitic stainless-steel products whose potential in laser powder bed fusion has been recently evaluated. This process allows manufacturing parts with complex shapes to be used in fields such as power generation, oil and gas, water treatment, petrochemical, and construction. The way of improving its properties is to promote dispersion hardening and to control texture. In this work, the effect of dispersion hardening and texture on the behavior at high temperature of a 316L steel was evaluated. Two 316L samples were manufactured by laser powder bed fusion, where the powder of one of them was inoculated with TiC nanoparticles. Advanced characterization proved that inoculation did not affect the solidification structure or the grain size, although it did modify the bulk texture.
