About this product
AVIMETAL 316L is a low-carbon, non-magnetic austenitic stainless steel powder for laser powder bed fusion (LPBF). With added molybdenum it delivers excellent general and chloride/pitting corrosion resistance, high toughness and good ductility, plus reliable weldability — the default stainless for corrosion-critical and biocompatible parts.
Produced by AVIMETAL, a leading specialist manufacturer of additive-manufacturing metal powders with in-house liquid-metal atomization and a strong track record across medical, marine and chemical-processing applications.
Why teams buy this powder from Additive Plus
- Genuine AVIMETAL 316L — gas-atomized for high sphericity, low oxygen and consistent flow.
- A strong value alternative to premium Western powders, at an accessible, published price.
- Available in small, workable volumes — no large mill minimums.
- Full COA with every lot — PSD, chemistry, apparent density and flow rate, with a traceable lot number.
- Fast dispatch from Los Angeles. Custom alloys / cuts via our own in-house atomization.

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% |
| Molybdenum (Mo) | 2.00–3.00% | Carbon (C) | ≤ 0.030% |
| 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.
