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.
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. Most replies in under 4 hours, NDA standard.
AVIMETAL 17-4PH is a martensitic, precipitation-hardening stainless steel powder for laser powder bed fusion (LPBF). It pairs high strength and hardness with good corrosion resistance and reliable performance up to 600°F (316°C), and age-hardens in a single, low-temperature step so you can dial in the strength-to-toughness balance your part needs.
Produced by AVIMETAL — a leading specialist manufacturer of additive-manufacturing metal powders with in-house liquid-metal atomization and a strong track record across aerospace, medical and automotive applications.
Why teams buy this powder from Additive Plus
- Genuine AVIMETAL 17-4PH — 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 — most mills sell large minimums and hide pricing behind an account; we stock it and sell it in accessible quantities.
- Full COA with every lot — particle size distribution, chemistry, apparent density and flow rate, with a traceable lot number.
- Fast dispatch from Los Angeles. Need a custom alloy or tighter cut? We also run our own atomization in-house for custom small-batch powder.
Standards & equivalents

Chemical composition
Typical chemistry (wt%) for 17-4PH stainless steel:
| Element | Content | Element | Content |
|---|---|---|---|
| Iron (Fe) | Balance | Manganese (Mn) | ≤ 1.00% |
| Chromium (Cr) | 15.00–17.50% | Silicon (Si) | ≤ 1.00% |
| Nickel (Ni) | 3.00–5.00% | Carbon (C) | ≤ 0.07% |
| Copper (Cu) | 3.00–5.00% | Phosphorus (P) | ≤ 0.040% |
| Niobium + Tantalum | 0.15–0.45% | Sulfur (S) | ≤ 0.030% |
Heat treatment & processing
- Age-hardenable in a single, low-temperature step (e.g. H900) — choose the condition to tune strength vs. toughness.
- Forgiving to print on commercial LPBF systems; stress relief recommended before part removal.
- Readily machined and finished in the solution-treated and aged conditions.
Key performance benefits
- Good strength, toughness, hardness and ductility
- Excellent response to precipitation (age) hardening
- Good corrosion resistance in industrial environments
- Stable mechanical properties up to 600°F (316°C)
- Well suited for functional parts and tooling
Typical applications
- Functional and structural production parts
- Valves, fittings and manifolds
- Pumps and impellers
- Rapid tooling and fixtures
- Industrial and chemical-processing equipment

From process engineers running 17-4PH Stainless Steel Alloy Powder for Metal 3D Printing | LPBF Compatible - 10 kg / 22 lbs
Unedited feedback from customers who reorder 17-4PH Stainless Steel Alloy Powder for Metal 3D Printing | LPBF Compatible - 10 kg / 22 lbs.
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.
