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 6 standard systems, each with the reason it does or does not match exactly. The full S355J2H data sheet carries the composition and mechanical tables.

S355J2H is cross-certified with S355J2: the composition windows overlap closely enough that one certificate satisfies the other. L360 / X52, A500 Grade C, A1085 and 4 more differ on one limit only — a carbon ceiling, an impact temperature or a strength minimum. S235JRH serves in the same applications, but the composition differs enough that the engineer signs it off, not the buyer. The cross-reference below covers 3 in EN (European), 1 in API (line pipe), 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. |
| L360 / X52 | API (line pipe) | Near | EN 10219 S355J2H: 355 MPa minimum yield with 27 J at −20 °C — almost the same strength and toughness, but it is a **structural** hollow section specification with no pipeline requirements: no yield ceiling, no carbon equivalent cap, no fracture-arrest testing. Suitable for a structural pipe, not for a transmission line. |
| 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.
