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).

| 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 to resist more severe environments, but with much lower strength than 17/4PH. |
| 2205 | Much better corrosion resistance than 17/4PH, with lower strength (but not as low as 316). |
Grade 630 stainless steels have good corrosion resistance in many environments. They exhibit improved resistance against stress corrosion cracking when aged at 550°C or higher. These steels should not be used in solution treated Condition A for corrosive environments.
Grade 630 stainless steels have good resistance to oxidation. However, long-time exposure to temperatures of 370 to 480°C should be avoided to prevent loss of toughness. These grades should not be used above age-hardening temperature to avoid reduction of hardness and mechanical properties.
Solution treatment (Condition A) - Heated at 1040°C for 0.5 h, then air-cooled to 30°C. Small sections can be oil quenched.
Hardening - Age-hardened at low temperatures to achieve required mechanical properties.

Grade 630 stainless steels can be welded using all conventional methods and do not require pre-heating. Care should be taken in designing and welding high strength steels to prevent weldment stresses.
Grade 630 stainless steels can be machined in their solution-treated condition. They have machining rates similar to grade 304 steels.
