S235JR equivalent grades: ASTM, EN, JIS, GB, DIN
S235JR is non-alloy hot-rolled structural steel specified in EN 10025-2. Below, the grades that can replace it — 7 standard systems in all — with the deciding limit named for each one rather than left to be looked up. The full S235JR data sheet carries the composition and mechanical tables.
Last updated
S235JR and St37-2, S235JRH are the same steel under different national numbers; a single mill certificate covers both. A36, A283 Gr. C, S235J0 and 7 more differ by one requirement, which is a line on the order rather than a redesign. St 22, S275JR, C15 and 4 more serve in the same applications, but the composition differs enough that the engineer signs it off, not the buyer. Across systems that is 2 in DIN (superseded German), 9 in EN (European), 2 in ASTM / ASME, 2 in GB/T (China), 1 in GOST (Russia/CIS), 2 in IS (India), 1 in JIS (Japan).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| St37-2 | DIN (superseded German) | Identical | Direct successor (1.0038). S235JR guarantees 27 J at +20 °C which St37-2 did not; ordering S235JR always satisfies an St37-2 requirement. |
| S235JRH | EN (European) | Identical | Same steel as flat/long product to EN 10025-2; the H suffix only marks the hollow-section delivery standard. |
| A36 | ASTM / ASME | Near | A36 yield 250 MPa (36 ksi) and Rm 400–550 MPa are slightly higher; no impact requirement. Widely accepted as the US counterpart. |
| A283 Gr. C | ASTM / ASME | Near | Yield 205 MPa, Rm 380–515 MPa; plate only, no Charpy requirement. |
| S235J0 | EN (European) | Near | Same chemistry limits with P/S 0.030 %; impact 27 J at 0 °C instead of +20 °C. |
| S195T | EN (European) | Near | The strip from which most S195T tube is actually made; S235JR coil certified to EN 10255 requirements. |
| Q235 | GB/T (China) | Near | GB/T 700 Q235B: yield 235 MPa, Rm 370–500 MPa, 27 J at +20 °C — the closest Chinese match; C max 0.20 %. |
| Q235 | GB/T (China) | Near | Q235B is the direct counterpart: same 235 MPa yield, same 27 J at +20 °C. Tensile floor is 10 MPa higher and Q235B carries a carbon minimum that S235JR does not. |
| St3sp | GOST (Russia/CIS) | Near | GOST 380 St3sp (killed): yield 245 MPa ≤ 20 mm, Rm 370–480 MPa; impact tested at +20 °C. |
| IS 2062 E250 BR | IS (India) | Near | Yield 250 MPa, Rm 410 MPa min; BR = impact tested at room temperature. |
| E250 | IS (India) | Near | The usual counterpart on quality structure: E250BR is tested to 27 J at room temperature as S235JR is at +20 °C. E250 is 250 MPa yield against 235 and 410 MPa tensile floor against 360, so it is the stronger of the two at both limits. |
| SS400 | JIS (Japan) | Near | JIS G3101 SS400: yield 245 MPa (≤16 mm), Rm 400–510 MPa; no chemistry limits beyond P and S, no impact test. |
| St 22 | DIN (superseded German) | Functional | Often offered as a substitute and often wrong: S235JR is a structural grade with a guaranteed yield and impact test, and it is less formable. Use it only if the part is structural rather than formed. |
| S275JR | EN (European) | Functional | Next strength class (275 MPa); substitutes upward for strength but is not identical. |
| C15 | EN (European) | Functional | Structural steel of similar carbon; not a case-hardening quality (no hardenability or cleanliness control). |
| DC01 | EN (European) | Functional | Hot-rolled structural steel of similar chemistry; not a cold-rolled forming grade and not interchangeable in surface or gauge. |
| DD11 | EN (European) | Functional | Structural steel of similar chemistry with guaranteed 235 MPa yield and impact; DD11 has no minimum yield guarantee for structural design. |
| P235GH | EN (European) | Functional | Same room-temperature yield and similar carbon, but no elevated-temperature proof values, looser P and S, and no normalising requirement. It cannot be substituted into a pressure calculation. |
| S250GD | EN (European) | Functional | Uncoated hot-rolled structural steel of similar strength for members that will be post-galvanized. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
