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® 304 / 304L is the most widely used chromium-nickel austenitic stainless steel, supplied as a low-carbon powder for laser powder bed fusion (LPBF) and EBM. It combines a high strength-to-weight ratio, good corrosion resistance and outstanding fabricability and weldability — a dependable, cost-effective stainless for general-purpose and corrosion-exposed parts.
It is non-magnetic in the annealed condition (becoming slightly magnetic when cold-worked) and is not hardenable by heat treatment.
Why teams buy this powder from Additive Plus
- Genuine Carpenter PowderRange® 304 — 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) | 18.00–20.00% | Silicon (Si) | ≤ 1.00% |
| Nickel (Ni) | 8.00–11.00% | Molybdenum (Mo) | ≤ 0.75% |
| Copper (Cu) | ≤ 0.75% | Carbon (C) | ≤ 0.030% |
| Phosphorus (P) | ≤ 0.040% | Sulfur (S) | ≤ 0.030% |
Heat treatment & processing
- 304 is not hardenable by heat treatment — strength comes from the as-built austenitic microstructure (and from cold work).
- Can be solution annealed to relieve stress and restore corrosion resistance.
- Excellent fabricability and weldability — one of the easiest stainless grades to print and post-process.
- Non-magnetic when annealed; becomes slightly magnetic after cold working.
Key performance benefits
- High strength-to-weight ratio
- Good corrosion resistance
- High toughness and ductility
- Excellent weldability and fabricability
- Non-magnetic (annealed), cost-effective stainless
Typical applications
- Medical devices
- Chemical-processing equipment
- Water and boiler components
- Valves, fittings and general industrial parts
