S235JRH equivalent grades: ASTM, EN, JIS, GB, DIN
S235JRH is non-alloy structural steel for cold-formed (EN 10219) and hot-finished (EN 10210) hollow sections 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 S235JRH data sheet carries the composition and mechanical tables.

Mills routinely dual-certify S235JRH as S235JR — the limits sit inside each other in both directions. A500 Grade B, Q235B (GB/T 6728), Ст3сп/пс (GOST 30245 / 8639) and 1 more sit one step away, differ in a strength minimum or in the quality class rather than in the metallurgy. Functionally interchangeable, S355J2H, S195T serve a different route to the same duty — check the design, not the analysis. The cross-reference below covers 3 in EN (European), 1 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 |
|---|---|---|---|
| S235JR | EN (European) | Identical | Same steel as flat/long product to EN 10025-2; the H suffix only marks the hollow-section delivery standard. |
| A500 Grade B | ASTM / ASME | Near | ASTM A500 Grade B cold-formed welded HSS: 290 MPa yield (round) / 317 MPa (shaped), 400 MPa tensile — the US box-section grade, slightly stronger than S235JRH; Grade C (345 MPa) ≈ S355J2H. |
| Q235B (GB/T 6728) | GB/T (China) | Near | Chinese cold-formed hollow sections on Q235B: 235 MPa yield, 370–500 MPa tensile, 27 J at +20 °C. |
| Ст3сп/пс (GOST 30245 / 8639) | GOST (Russia/CIS) | Near | CIS square and rectangular tube on Ст3 steel, 245 MPa yield class. |
| STKR400 / STK400 | JIS (Japan) | Near | JIS G3466 (rectangular) / G3444 (circular) structural tube: yield ≥ 245 MPa, tensile ≥ 400 MPa. |
| S355J2H | EN (European) | Functional | The high-strength hollow-section grade for primary members and EN 1090 EXC2/3 components. |
| S195T | EN (European) | Functional | EN 10255 pipe steel for water/gas lines — not a structural grade; use S235JRH when the tube is a member. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
