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.
