S355J2H in other standards
Full comparison“Equivalent” tables online usually match grades by name. This one compares the values each standard actually guarantees, so a 30 MPa gap in yield is visible before it is in your calculation.

|---|---|---|---|---|---|
| S355J2H |  EN 10219-1 | ≥ 355MPa2 | 470–630MPa3 | — | Reference grade. |
| A500 Grade C |  ASTM A500/A500M | ≥ 345MPa2 | ≥ 425MPa2 | Approximate | Shaped A500 Grade C guarantees 345 MPa (50 ksi) and only 425 MPa tensile; round tubes only 315 MPa (46 ksi). No impact test. |
| A1085 | ASTM A1085/A1085M | 345–483MPa1 | ≥ 450MPa1 | Approximate | 345 MPa (50 ksi) yield with a 70 ksi cap, 450 MPa tensile, tighter wall tolerance; designed for seismic and full-thickness design. |

Missing on purpose: a value appears here only once a public source states it.
Sources here are public pages that reproduce EN 10219-1. For design and acceptance, the standard edition named in your specification and the inspection certificate (EN 10204 3.1) of the delivered product take precedence.
