Material Description
17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and moderate corrosion resistance. High strength is maintained to approximately 600°F (316°C).
General Properties
Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance. Mechanical properties can be optimized with heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).

Alternative Grades Comparison
| Alternative Grade | Comparison |
|---|---|
| 431 | Higher toughness than 17-4PH, better availability in some sizes |
| 416 | Free-machining martensitic stainless steel, better for repetition machining, lower cost |
| 316 | Higher corrosion resistance but with much lower strength than 17-4PH |
| 2205 | Much better corrosion resistance with lower strength (but not as low as 316) |
