Alternative Grade Comparison
| Alternative Grade | Reasons for Choosing 17-4PH (630) |
|---|---|
| 431 | 431 has higher toughness but 17-4PH offers better strength |
| 416 | 416 is free-machining with lower cost but lower strength |
| 316 | 316 has higher corrosion resistance but much lower strength |
| 2205 | 2205 has much better corrosion resistance with lower strength |
