Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| S355J2 | EN (European) | Identical | Same steel as plate, strip and sections to EN 10025-2; H marks the hollow-section standard. |
| A500 Grade C | ASTM / ASME | Near | ASTM A500 Grade C cold-formed welded HSS: 317 MPa (round) / 345 MPa (shaped) yield, 427 MPa tensile — the US structural box-section grade; A1085 (345 MPa, tighter tolerances, 25 J at 4 °C) is closer to EN 10219 S355J2H. |
| A1085 | ASTM / ASME | Near | ASTM A1085 HSS: 345 MPa yield, 450 MPa tensile, Charpy option, tolerances aligned with EN 10219 — the closest US specification. |
| S420MH | EN (European) | Near | Thermomechanical high-strength hollow-section grade of EN 10219 for weight-critical trusses. |
| Q355B / Q355D (GB/T 6728) | GB/T (China) | Near | Chinese cold-formed hollow sections on Q355: 355 MPa yield; D quality has 27 J at −20 °C like J2H. |
| 09Г2С (GOST 30245) | GOST (Russia/CIS) | Near | CIS square and rectangular tube on 09Г2С low-alloy steel, 345 MPa yield, −40 °C impact. |
| STKR490 / STK490 | JIS (Japan) | Near | JIS G3466 / G3444 structural tube: yield ≥ 325 MPa, tensile ≥ 490 MPa. |
| S235JRH | EN (European) | Functional | The general-purpose hollow-section grade for light frames and fences. |
Identical = same composition and mechanical limits within rounding. Near = one limit differs (e.g. carbon max or impact temperature). Functional = interchangeable for most uses after an engineering check.
How the matches are graded
Identical means the chemical composition windows overlap so that material certified to one specification meets the other without deviation, and the mechanical minimums are the same or the other is inside them — mills usually dual-certify. Near means one limit differs (a carbon maximum, an impact temperature, a strength minimum or a delivery condition) and a substitution needs a one-line engineering check. Functional means the grades serve the same purpose but are not the same steel — a designer can often use one for the other, but only after re-checking the design.
