Mechanical
| Property | Condition | SD345 | A706 Grade 60 | Difference |
|---|---|---|---|---|
| Yield strength ReH | — | 345–440MPa1 | 420–540MPa1 | +22 % |
| Tensile strength Rm | — | ≥ 490MPa1 | ≥ 550MPa1 | +12 % |
Rows are matched by condition (thickness band, temperature, product form). A dash means the grade has no sourced value for that condition. Differences are A706 Grade 60 relative to SD345; for ranges the lower bound is compared.
