316L is the most widely used austenitic stainless steel powder for additive manufacturing, providing reliable corrosion resistance in chloride-bearing, acidic, and high-humidity environments. Its low carbon content minimizes carbide precipitation during processing, supporting good inter-granular corrosion resistance. Qualified to ASTM A276 and EN 1.4404, it is used across automotive, defense, power generation, and general industrial applications for fluid handling components, structural hardware, heat exchangers, and medical devices where cleanability and corrosion resistance are primary requirements.
