17-4PH Stainless Steel Powder for LPBF — 15–45 µm, 10 kg
Carpenter 17-4PH Stainless Steel powder price: $545 per 10 kg ($54.50/kg)
Martensitic precipitation-hardening stainless steel for tooling and functional parts, age-hardened by a single low-temperature treatment. Vacuum-induction-melted and nitrogen-atomized by Carpenter Additive (PowderRange 17-4). For full wrought-type properties, Carpenter recommends 17-4 AR.
* Carpenter data with 20–60 µm layers and specific energy ≥ 50 J/mm³.

What the particles look like
From the manufacturer datasheet

Each lot ships with a Carpenter certificate listing chemistry, D10/D50/D90, Hall flow and apparent density — available on request.
How the printed metal performs
Carpenter does not publish tensile data on the PowderRange 17-4 datasheet. Its higher nitrogen can stop full transformation to martensite, giving slightly lower properties than 17-4 AR; for typical wrought 17-4 properties Carpenter recommends 17-4 AR, whose data is on its page.
Heat treatment
Carpenter datasheet, process guidance
- Stress relief: 677 °C (1250 °F), 1 hour per inch of thickness, minimum 2 hours, up to 4 hours.
- Homogenize to reduce anisotropy: 1093 °C (2000 °F) for 1 hour, air cool. Not needed if you HIP.
- HIP to close porosity: at least 100 MPa (14.5 ksi) at about 1141 °C (2087 °F) for about 240 minutes in argon.
- Solution anneal per ASTM A564: 1038 °C (1900 °F) for 0.5 hour, cool below 32 °C (90 °F). Then age, for example H900: 482 °C (900 °F) for 1 hour, air cool.
- Carpenter advises against using the solution-annealed condition without aging, because of stress-corrosion cracking.
- Because of its higher nitrogen, PowderRange 17-4 may not transform fully to martensite during heat treatment.
