A615 Grade 60 vs SD345
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.
JIS G 3112 · Steel
Japanese deformed bar: yield 345–440 MPa, tensile ≥ 490 MPa, yield ratio ≤ 80 %.
Mechanical
| Property | Condition | A615 Grade 60 | SD345 | Difference |
|---|---|---|---|---|
| Yield strength ReH | — | ≥ 420MPa1 | 345–440MPa1 | −18 % |
| Tensile strength Rm | — | ≥ 620MPa1 | ≥ 490MPa1 | −21 % |
Rows are matched by condition (thickness band, temperature, product form). A dash means the grade has no sourced value for that condition. Differences are SD345 relative to A615 Grade 60; for ranges the lower bound is compared.
