| Alternative 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). |
