Engineering focus: 17-4PH stainless steel powder
Review the material, particle-size, process and validation factors that matter for this application.
Suitable for load-bearing or structural parts that require a balance of properties, not high hardness alone.
It should be judged together with feedstock, cavity filling and sintering shrinkage.
Part wall thickness, dimensions and subsequent heat treatment can affect the final solution.
Material properties of 17-4PH powder
17-4PH is a commonly used precipitation hardening stainless steel, suitable for precision parts that require high strength, corrosion resistance and heat treatment adjustability at the same time. The powder route also supports complex shapes and near-net-shape finished products.
Typical applications and manufacturing processes
Can be used in MIM precision structural parts, tool components, lock hardware, consumer electronics and small automotive parts. When selecting, focus on powder particle size, feedstock flow, debinding sintering, shrinkage control and subsequent aging treatment.
- Metal injection molding precision parts
- High-strength corrosion-resistant structural parts
- Tools, Locks and Consumer Hardware
- Automotive and Industrial Connecting Parts
Tongcheng 17-4PH particle size parameter
The volume-based particle size test record dated 2025-05-03 shows D10 of 2.362 μm, D50 of 8.706 μm and D90 of 30.630 μm for 17-4PH. The particle size specification for supply can be confirmed with reference to part wall thickness, the feedstock system and the sintering process.
