Description
SS 316L Micron Powder for Additive Manufacturing, Size: 15-45 µm, Spherical
SS 316L Micron Powder for Additive Manufacturing is a premium-grade spherical stainless steel powder engineered specifically for 3D metal printing applications. With a precisely controlled particle size distribution of 15-45 µm, this high-purity powder delivers exceptional performance in advanced additive manufacturing processes including Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS), Electron Beam Melting (EBM), and binder jetting.
Our 316L stainless steel powder features an ultra-low carbon content (0.02% max), ensuring superior weldability and outstanding corrosion resistance. The spherical morphology guarantees excellent flowability, uniform powder bed formation, and high packing density—critical factors for achieving near-full density parts (≥99.5%) with minimal porosity in metal 3D printing.
Enhanced with 2% molybdenum, this austenitic stainless steel powder exhibits remarkable resistance to pitting and crevice corrosion in chloride environments, making it ideal for marine, chemical processing, and medical applications. The 316L powder maintains consistent mechanical properties with yield strength of 320 ± 10 MPa and tensile strength of 550 ± 30 MPa in as-built conditions.
