PowderRange 304L is a low carbon, austenitic stainless steel that exhibits a high strength-to-weight ratio and 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 304L cannot be strengthened through post processing heat treatments but can be solution annealed to improve corrosion resistance. It is non-magnetic in the annealed condition. Post processing can include traditional machining, abrasive flow machining, shot-peening, grinding, polishing, chemical milling/etching, and other methods.
