S355J2H / Equivalents
Is it really S355J2H? 2 “equivalents” checked
Cross-reference tables pair grades by name and history. Here each pairing is judged on the minimum values each standard guarantees, with the sources for both sides.
Same strength class; guaranteed values agree within a few MPa. Still check thickness bands and impact quality.
Same class of steel, but at least one guaranteed value is lower or tested differently. Recheck the design.
A500 Grade CASTM- A1085ASTM
Commonly listed as an equivalent, but the guaranteed values do not support substitution.
Side by side
| Grade | Standard | Min. yield at 10 mm | Tensile at 10 mm | Match | What differs |
|---|---|---|---|---|---|
| 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. |
