About this product
A-Powder SS316L is a high-grade stainless steel powder developed for LPBF additive manufacturing. Produced via nitrogen gas atomization and vacuum induction melting, the powder has a uniform, spherical particle morphology (15–53 µm) with low oxygen content (≤800 ppm), providing stable powder flow, smooth recoating, and repeatable layer fusion. The alloy composition (Fe balance, Cr 16.71 %, Ni 10.63 %, Mo 2.3 %) delivers excellent corrosion resistance and mechanical performance. After heat treatment, components reach ultimate tensile strength of 590 MPa, yield 380 MPa, and elongation of 60 %, making SS316L ideal for surgical instruments, medical implants, aerospace brackets, and industrial machinery. A-Powder SS316L ensures consistent quality, small-batch flexibility, and fast delivery with full traceable documentation from AO Metal.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
