SD390 vs A615 Grade 60
JIS G 3112 · Steel
Japanese deformed bar: yield 390–510 MPa, tensile ≥ 560 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 | SD390 | A615 Grade 60 | Difference |
|---|---|---|---|---|
| Yield strength ReH | — | 390–510MPa1 | ≥ 420MPa1 | +7.7 % |
| Tensile strength Rm | — | ≥ 560MPa1 | ≥ 620MPa1 | +11 % |
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 SD390; for ranges the lower bound is compared.
