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
| Grade | Reasons for choosing 17/4PH (630) |
|---|---|
| 431 | 431 Has 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 of 316 to resist more severe environments, but with much lower strength than 17/4PH. |
| 2205 | Much better corrosion resistance than 17/4PH, with a lower strength (but not as low as 316). |
