GEN 316L Overview
GEN 316L shares the same characteristics as GEN 316, except for the lower carbon content. GEN 316L is primarily used for welding low‐carbon molybdenum‐bearing austenitic alloys. The lower carbon content reduces the possibility of intergranular chromium carbide precipitation and thus increases the resistance against intergranular corrosion.
