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® 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 unlike most stainless grades, it can be age-hardened in a single, low-temperature step, so you can dial in the exact strength-to-toughness balance your part needs.
It is one of the most widely qualified alloys in metal additive manufacturing, used for functional production parts, rapid tooling, and corrosion-resistant components across aerospace, medical, energy, and industrial markets.
Why teams buy this powder from Additive Plus
- Genuine Carpenter PowderRange® 17-4 — vacuum-induction melted and nitrogen gas-atomized for tight, repeatable chemistry and high sphericity.
- Available in small, workable volumes. Most mills sell large minimums and hide pricing behind an account. We sell this alloy 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.
- Currently on backorder — we confirm the ship date when you order.
- 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) | ≤ 1.00% |
| Chromium (Cr) | 15.00–17.50% | Silicon (Si) | ≤ 1.00% |
| Nickel (Ni) | 3.00–5.00% | Carbon (C) | ≤ 0.07% |

| Oxygen (O) | ≤ 0.10% | Sulfur (S) | ≤ 0.030% |
Heat treatment & process guidance
17-4PH is forgiving to print and simple to post-process. Carpenter’s recommended routes:
- As-built: mean density >99.9% is achievable on commercial LPBF systems with 20–60 µm layers and specific energy of at least 50 J/mm³.
- Stress relief: 1250°F (677°C), about 1 hour per inch of thickness.
- Homogenization: 2000°F (1093°C) for 1 hour, air cool — minimizes anisotropy (not needed if HIP’d).
- HIP (optional, for full density): about 2087°F (1141°C) at no less than 14.5 ksi (100 MPa) for ~4 hours under argon.
- Solution anneal + age (H900): solution anneal 1900°F (1038°C), then age 900°F (482°C) for 1 hour and air cool, per ASTM A564/A564M.
Note: PowderRange 17-4 runs slightly higher in nitrogen, so full martensite transformation may not occur on heat treatment. If you need cast/wrought-equivalent properties, ask us about 17-4 AR.
