17-4 PH Stainless Steel Powder
17-4 PH Stainless Steel Powder Supplier and Exporter
17-4 PH Stainless Steel powder (S17400) is a argon or nitrogen gas atomised precipitation-hardening stainless steel feedstock for additive manufacturing, supplied to ASTM F3301 (PBF post-processing) in 5-25 µm, 15-45 µm, 15-53 µm, 45-105 µm, 53-105 µm, 45-150 µm, 53-150 µm size fractions.
Reaches over 1300 MPa after a simple H900 age, which makes it the default when a printed stainless part has to carry real load.

What Properties Does Printed 17-4 PH Reach?
Printed properties depend on the heat treatment, not just the alloy, so they are given per condition.
| Condition | Tensile strength | Yield strength | Elongation | Hardness |
|---|---|---|---|---|
| As built | 900-1100 MPa | 600-800 MPa | 10-20% | 30-35 HRC |
| H900, aged at 480 C | 1300-1400 MPa | 1150-1250 MPa | 10-15% | 40-44 HRC |
| H1150, aged at 620 C | 950-1050 MPa | 800-900 MPa | 16-20% | 28-33 HRC |
Printed 17-4 PH normally needs solution treatment before ageing, because the as-built structure retains austenite that a straight age will not convert.
Which Processes Can 17-4 PH Powder Be Used In?

What Is 17-4 PH Powder Used For?
Tooling, aerospace brackets, valve and pump components, and moulds.
Post-processing
Solution treat then age - H900 for maximum strength, H1025 or H1150 where toughness matters more.
Should I use 17-4 PH or 316L powder?
Use 17-4 PH where a printed stainless part has to carry real load, since aged to H900 it reaches 1300-1400 MPa. Use 316L where corrosion resistance, ductility and ease of printing matter more than strength, as in chemical, food and marine parts.
Characterisation and Packing
Each batch is supplied with chemical analysis, particle size distribution by laser diffraction to ASTM B822, apparent and tap density, and flow rate by Hall or Carney funnel. Morphology imaging, oxygen and nitrogen analysis and reporting to ISO/ASTM 52907 are available where your qualification requires them.
Powder is packed under argon in sealed containers with desiccant, labelled with lot number, alloy, particle size cut and date of atomisation.
