A615 Grade 60 vs SD390
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 390–510 MPa, tensile ≥ 560 MPa, yield ratio ≤ 80 %.
Mechanical
| Property | Condition | A615 Grade 60 | SD390 | Difference |
|---|---|---|---|---|
| Yield strength ReH | — | ≥ 420MPa1 | 390–510MPa1 | −7.1 % |
| Tensile strength Rm | — | ≥ 620MPa1 | ≥ 560MPa1 | −9.7 % |
Rows are matched by condition (thickness band, temperature, product form). A dash means the grade has no sourced value for that condition. Differences are SD390 relative to A615 Grade 60; for ranges the lower bound is compared.
