S235JRH equivalent grades: ASTM, EN, JIS, GB, DIN
Cross-reference for S235JRH across standard systems. Each match is graded so you can see how safe the substitution is. Non-alloy structural steel for cold-formed (EN 10219) and hot-finished (EN 10210) hollow sections — full S235JRH data sheet.
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 = 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.
