Stainless spring steel strip EN 10151
Cold worked conditions:
| Cond. | Tensile Strength, Rm [MPa] |
| +C700 | 700 - 850 |
| +C850 | 850 - 1000 |
| +C1000 | 1000 - 1150 |
| +C1150 | 1150 - 1300 |
| +C1300 | 1300 - 1500 |
| +C1500 | 1500 - 1700 |
| +C1700 | 1700 - 1900 |
| +C1900 | 1900 - 2200 |
Intermediate tensile strengths may be agreed. Alternatively, the steels may be specified in terms of minimum 0,2% proof strength or hardness, but only one parameter can be specified in one order.
