UNS #S31600/S31603

PowderRange® 316L is a low carbon, non-magnetic, austenitic stainless steel that exhibits moderate to good strength, good fracture toughness, and has generally good corrosion resistance, especially intergranular corrosion. It has excellent weldability in laser and electron-beam additive manufacturing processes and can be processed in either argon or nitrogen shielding gas. PowderRange® 316L cannot be strengthened through post processing heat treatments but can be solution annealed to improve corrosion resistance. Solution annealing is application-specific, but is generally not necessary for most situations. Post processing can include traditional machining, abrasive flow machining, shot-peening, grinding, polishing, chemical milling/etching, and other methods.
