SD490 vs A615 Grade 60
JIS G 3112 · Steel
Japanese deformed bar: yield 490–625 MPa, tensile ≥ 620 MPa, yield ratio ≤ 80 %.
ASTM A615/A615M · Steel
The common US rebar: 60 ksi (420 MPa) yield. Not intended for welding; use A706 where welding or seismic ductility matters.
Mechanical
| Property | Condition | SD490 | A615 Grade 60 | Difference |
|---|---|---|---|---|
| Yield strength ReH | — | 490–625MPa1 | ≥ 420MPa1 | −14 % |
| Tensile strength Rm | — | ≥ 620MPa1 | ≥ 620MPa1 | same |
Rows are matched by condition (thickness band, temperature, product form). A dash means the grade has no sourced value for that condition. Differences are A615 Grade 60 relative to SD490; for ranges the lower bound is compared.
