S355J2H vs A500 Grade C
EN 10219-1 · Steel
Cold-formed welded hollow sections (SHS, RHS, CHS): 355 MPa yield, 470–630 MPa tensile, 27 J at −20 °C.
ASTM A500/A500M · Steel
The usual US HSS grade: 50 ksi (345 MPa) yield shaped, 46 ksi (315 MPa) round, 62 ksi (425 MPa) tensile.
ApproximateShaped A500 Grade C guarantees 345 MPa (50 ksi) and only 425 MPa tensile; round tubes only 315 MPa (46 ksi). No impact test.
Mechanical
| Property | Condition | S355J2H | A500 Grade C | Difference |
|---|---|---|---|---|
| Tensile strength Rm | t = 3 mm | 510–680MPa2 | ≥ 425MPa2 | −17 % |
| t = 40 mm | 470–630MPa3 | ≥ 425MPa2 | −9.6 % |
Rows are matched by condition (thickness band, temperature, product form). A dash means the grade has no sourced value for that condition. Differences are A500 Grade C relative to S355J2H; for ranges the lower bound is compared.
