What your process engineer actually checks
Locked, traceable lot chemistry
A COA on request documents PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. NDA standard.
PowderRange® 316L is a low-carbon, non-magnetic austenitic stainless steel powder for laser powder bed fusion (LPBF) — and also EBM and DED. With added molybdenum it delivers excellent general and chloride/pitting corrosion resistance, high impact toughness and good ductility, plus reliable weldability, making it the default stainless for corrosion-critical and biocompatible parts.
It is one of the most widely used alloys in metal additive manufacturing, found in marine, chemical-processing, aerospace, transportation and medical-implant applications.
Why teams buy this powder from Additive Plus
- Genuine Carpenter PowderRange® 316L — gas-atomized for high sphericity, low oxygen and consistent flow.
- Available in small, workable volumes. Most mills sell large minimums and hide pricing behind an account. We stock this alloy and sell it in accessible quantities at a clear, published price.
- COA on request — particle size distribution, chemistry, apparent density and flow rate, with a traceable lot number.
- In US stock — ready to ship. Order online in minutes.
- Need a custom alloy or a tighter cut? We also run our own atomization in-house and can produce custom small-batch powder on request — separate from this stocked product.

Chemical composition
Typical chemistry (wt%), per the Carpenter PowderRange® datasheet:
| 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% |

| Carbon (C) | ≤ 0.030% | Phosphorus (P) | ≤ 0.045% |
| Sulfur (S) | ≤ 0.030% |
Heat treatment & processing
- 316L cannot be strengthened by heat treatment (no age hardening) — properties come from the as-built austenitic microstructure.
- Solution annealing is optional and application-specific; it can be used to improve corrosion resistance, but is not required for most parts.
- Excellent weldability in laser and electron-beam AM; can be processed under argon or nitrogen shielding gas.
- Post-processing options: traditional machining, abrasive flow machining, shot-peening, grinding, polishing, and chemical milling / etching.
Key performance benefits
- High impact toughness and good ductility
- Moderate strength and creep resistance
