A500 Grade C vs S355J2H
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.
EN 10219-1 · Steel
Cold-formed welded hollow sections (SHS, RHS, CHS): 355 MPa yield, 470–630 MPa tensile, 27 J at −20 °C.
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 | A500 Grade C | S355J2H | Difference |
|---|---|---|---|---|
| Tensile strength Rm | t = 3 mm | ≥ 425MPa2 | 510–680MPa2 | +20 % |
| t = 40 mm | ≥ 425MPa2 | 470–630MPa3 | +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 S355J2H relative to A500 Grade C; for ranges the lower bound is compared.
