Mechanical
| Property | Condition | A706 Grade 60 | SD490 | Difference |
|---|---|---|---|---|
| Yield strength ReH | — | 420–540MPa1 | 490–625MPa1 | +17 % |
| Tensile strength Rm | — | ≥ 550MPa1 | ≥ 620MPa1 | +13 % |
Rows are matched by condition (thickness band, temperature, product form). A dash means the grade has no sourced value for that condition. Differences are SD490 relative to A706 Grade 60; for ranges the lower bound is compared.
