Product Overview
AM-316L-15D is a premium-grade, gas-atomized 316L stainless steel powder engineered specifically for high-precision additive manufacturing (AM) processes including laser powder bed fusion (LPBF) and binder jetting. As a certified 3d printing powders solution, it delivers exceptional consistency, sphericity, and flowability—critical for repeatable part quality and high-density builds. This ASTM F3049-compliant and ISO 13320-certified metal powder meets stringent aerospace, medical, and industrial standards for chemical composition, particle size distribution, and contamination control.
With its tightly controlled 15–45μm particle size range, AM-316L-15D ensures optimal packing density and layer uniformity—minimizing porosity and maximizing mechanical performance in final components. Its low oxygen content (<0.025 wt%), high sphericity (>95%), and narrow D10–D90 spread support stable melt pool dynamics and superior surface finish in demanding AM applications.
Key Features
- Gas-atomized for high sphericity (>95%) and excellent flowability (≤25 s/50g, Hall Flow)
- ASTM F3049 and ISO 13320 certified for particle size distribution and morphology
- Ultra-low oxygen and nitrogen content for enhanced corrosion resistance and ductility
- Consistent batch-to-batch reproducibility—ideal for serial production and qualification-critical parts
- Optimized for LPBF, EBM, and binder jetting systems (e.g., EOS, SLM Solutions, HP Metal Jet)

Applications
This high-performance 316L stainless steel powder is widely deployed across industries requiring biocompatibility, corrosion resistance, and structural integrity. Key use cases include: surgical instruments and dental implants (leveraging its ASTM F3049 compliance for medical AM); marine and chemical processing components; lightweight heat exchangers and fluidic manifolds; aerospace brackets and ducting; and functional prototypes in automotive and energy sectors. As a benchmark 15–45μm metal powder, AM-316L-15D enables reliable, scalable production of complex, net-shape parts where traditional 3d printing powders fall short in consistency or certification rigor.
