C. Comparative Advantages
vs. 17-7PH (Alloy 631)
| Property | 17-4PH (Alloy 630) | 17-7PH (Alloy 631) |
|---|---|---|
| Strengthening Phase | Cu precipitates (Cu₂Ni) | Ni₃Al precipitates |
| Max Hardness | 44 HRC (H900) | 45 HRC (RH950) |
| Corrosion Resistance | Slightly better than 304 SS | Similar to 304 SS |
| Typical Uses | Valves, shafts, molds | Springs, aerospace thin-walled parts |
vs. Conventional Martensitic Steels (e.g., 410)
Higher Strength: Yield strength 1.5–2× that of 410 steel.
Better Dimensional Stability: Low aging temperatures (≤620°C) minimize distortion (<0.1%), ideal for precision components.
