S355J2H equivalent grades: ASTM, EN, JIS, GB, DIN
S355J2H is non-alloy structural steel for hollow sections, 355 MPa, −20 °C impact specified in EN 10219. Every grade in the database that can stand in for it is listed below, drawn from 5 standard systems, each with the reason it does or does not match exactly. The full S355J2H data sheet carries the composition and mechanical tables.
Last updated
For S355J2H the exact matches are S355J2, and material bought as one is accepted as the other without deviation. A500 Grade C, A1085, S420MH and 3 more differ on one limit only — a carbon ceiling, an impact temperature or a strength minimum. At the functional level S235JRH serves as a replacement once the design has been re-run. The table holds 3 in EN (European), 2 in ASTM / ASME, 1 in GB/T (China), 1 in GOST (Russia/CIS), 1 in JIS (Japan).
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, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
