A 630 phaj hlau yog martensitic, chromium-nickel-tooj liab nag lossis daus-hardening stainless hlau. A 630 phaj hlau muaj peev xwm ua tau ntau yam ntawm lub zog thiab cov khoom tawv tawv nyob ntawm seb qhov dej nag lossis kev laus siv hauv 630 phaj steel hardening.
| Cr | 15,0 - 17,0 |
| Ni | 3,0-5,0 |
| Cu | 3,0-5,0 |
| C | max 0,070 |
Nws muaj qhov tsawg kawg nkaus tawm lub zog ntawm 790 MPa thaum hardened ntawm 593 Celsius. Nws yog raug rau brittle fractures.
17-4ph h900 clad phaj siv qhov kub ntawm 900 Fahrenheit rau 4 teev los ua kom cov khoom tawv. Txawm li cas los xij, kev ua haujlwm thermal txiav yuav tsum raug zam rau qhov no, es tsis txhob, kev siv tshuab txiav yuav tsum tau siv.
