Powdered metal in Stainless steel 17-4 PH (H900)
Stainless steel 17-4 PH (H900) is a proven choice for powdered metal: tensile strength from about 145 ksi (h1150) to 200 ksi (h900) by choice of aging temperature. On a representative spur gear at 25,000 pieces it estimates at about $1.42 per part plus $7,938 tooling, with a lead time of 6–9 weeks. Typical tolerance is About ±0.001 in per in (±0.1%) as sintered; about ±0.0005 in (±0.013 mm) after sizing.

17-4 PH vs other powdered metal materials
The same spur gear at 25,000 pieces, priced in every material the process runs. FC-0208 is the lowest all-in cost.
| Material | Per part | All-in | Weight | Tensile |
|---|---|---|---|---|
| Powder metal FC-0208 (copper steel) | $0.43 | $0.76 | 65 g | 410 MPa |
| Powder metal FN-0205 (nickel steel) | $0.50 | $0.84 | 67 g | 340 MPa |
| Powder metal SS-316L (stainless) | $1.24 | $1.58 | 65 g | 330 MPa |
| Stainless steel 17-4 PH (H900) | $1.42 | $1.76 | 75 g | 1379 MPa |

Strengths
- Tensile strength from about 145 ksi (H1150) to 200 ksi (H900) by choice of aging temperature
- Aging at 900–1,150 °F (482–621 °C) causes little distortion, so parts are machined near final first
- Corrosion resistance comparable to 304
- Available as bar, plate, forgings, MIM feedstock and AM powder
Watch for
- H900 has low impact toughness; use H1025–H1150 for impact or stress corrosion concerns
- Condition A is about 35 HRC, so machining is slow and hard on tools
- Magnetic, unlike 300-series grades
- Loses toughness with long exposure above about 600 °F (315 °C)

Questions
How much does powdered metal in 17-4 PH cost?
For a representative part (spur gear 24t, module 1.5, 10 mm face, ø8 mm bore), SSG's estimator gives about $1.42 per part at 25,000 pieces, plus about $7,938 one-time tooling. All-in with tooling and setup that is $1.76 per part. It is budgetary; principals quote firm prices from your drawing.
Is 17-4 PH a good material for powdered metal?
It is when you need tensile strength from about 145 ksi (h1150) to 200 ksi (h900) by choice of aging temperature and aging at 900–1,150 °f (482–621 °c) causes little distortion, so parts are machined near final first. Watch for h900 has low impact toughness; use h1025–h1150 for impact or stress corrosion concerns. Of 4 materials run in powdered metal, it ranks 4 on all-in cost for the same part.
What finishes work on 17-4 PH powdered metal parts?
Common options are bead blasted, vibratory deburr (tumbling), passivation, laser marking, heat treating. The builder adds each finish's lot charge, per-part cost and days to the estimate.
What tolerance can powdered metal hold in 17-4 PH?
Typical capability is About ±0.001 in per in (±0.1%) as sintered; about ±0.0005 in (±0.013 mm) after sizing. Tighter tolerances are possible on called-out features at added cost; specify them on the drawing rather than as a blanket note.
