What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.

Chemical composition
Typical chemistry (wt%) for 316L:
| Element | Content | Element | Content |
|---|---|---|---|
| Iron (Fe) | Balance | Manganese (Mn) | ≤ 2.00% |
| Chromium (Cr) | 16.0–18.0% | Silicon (Si) | ≤ 1.00% |
| Nickel (Ni) | 10.0–14.0% | Nitrogen (N) | ≤ 0.10% |

| Phosphorus (P) | ≤ 0.045% | Sulfur (S) | ≤ 0.030% |
Heat treatment & processing
- 316L cannot be precipitation hardened — properties come from the as-built austenitic microstructure.
- Solution annealing is optional and application-specific; it can improve corrosion resistance.
- Excellent weldability; can be processed under argon or nitrogen shielding gas.
Key performance benefits
- High impact toughness and good ductility
- Excellent general and intergranular corrosion resistance
- Non-magnetic, biocompatible austenitic stainless
- Excellent weldability for laser AM
Typical applications
- Medical implants and instrumentation
- Valves, fittings and manifolds
- Pumps and impellers
- Marine and chemical-processing components

★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

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.

What is SS316L Powder?
SS316L is an austenitic stainless steel powder engineered for LPBF additive manufacturing. It combines high strength, corrosion resistance, and reproducible mechanical performance for critical end-use components.
Which additive manufacturing processes are compatible?
Optimized for LPBF, and compatible with EBM and DED. Spherical particles (15–53 µm) and low oxygen content ensure smooth recoating, minimal spatter, and predictable layer fusion.
Can printed parts be heat treated?
Yes, post-processing heat treatment enhances mechanical properties, achieving UTS 590 MPa, yield 380 MPa, and elongation 60 %.
What industries commonly use SS316L powder?
Aerospace, Medical & Dental, Automotive & Transportation, and Industrial Machinery.
Why choose A-Powder SS316L?
Manufactured by AO Metal with small-batch flexibility, high-quality control, rapid delivery, and full traceable documentation, ensuring reliable, production-ready LPBF performance.
How does 316L perform in corrosive environments? in standard industrial 3D printers?
316L provides good resistance to general and intergranular corrosion, making it suitable for use in humid, chemically aggressive, and industrial environments.
Can I order a smaller quantity or a custom particle size?
Yes. We sell in small, workable volumes with no large mill minimums, and we can supply custom particle-size cuts or quantities on request - just ask us for a quote.
