S355J2 equivalent grades: ASTM, EN, JIS, GB, DIN
S355J2 is non-alloy hot-rolled structural steel, −20 °C impact 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 S355J2 data sheet carries the composition and mechanical tables.
Last updated
Mills routinely dual-certify S355J2 as St52-3, S355J2H — the limits sit inside each other in both directions. The near matches are A572 Grade 50, A709 Gr. 50, S355JR and 7 more; what differ is the tested condition, not the alloy. S355J2W, S355MC serve in the same applications, but the composition differs enough that the engineer signs it off, not the buyer. Across systems that is 1 in DIN (superseded German), 5 in EN (European), 2 in ASTM / ASME, 2 in GB/T (China), 2 in GOST (Russia/CIS), 1 in IS (India), 1 in JIS (Japan).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| St52-3 | DIN (superseded German) | Identical | Successor of St52-3 N (1.0577); same yield table, tensile 470–630 MPa, 27 J at −20 °C, cleaner P/S. |
| S355J2H | EN (European) | Identical | Same steel as plate, strip and sections to EN 10025-2; H marks the hollow-section standard. |
| A572 Grade 50 | ASTM / ASME | Near | Yield 345 MPa, Rm 450 MPa min; order with supplementary S5 (Charpy) to approach J2 toughness. |
| A709 Gr. 50 | ASTM / ASME | Near | Bridge version of A572-50 with Charpy requirement by zone; closest US match for bridge plate. |
| S355JR | EN (European) | Near | Same strength; JR tested at +20 °C, higher P/S allowed. |
| S355N | EN (European) | Near | EN 10025-3 normalized fine-grain steel, same strength up to 16 mm, better guaranteed toughness and weldability (Nb/V/Ti grain refinement). |
| Q355 | GB/T (China) | Near | GB/T 1591 Q355D: 355 MPa yield, 34 J at −20 °C; quality D is the −20 °C class matching J2. |
| Q355 | GB/T (China) | Near | Q355D matches it: −20 °C impact test, P ≤ 0.025 % and S ≤ 0.020 %, and a fine-grain aluminium requirement. |
| 09G2S-12 | GOST (Russia/CIS) | Near | Category 12 = impact at −40 °C; low-alloy 09G2S exceeds S355J2 toughness but yield is 325–345 MPa. |
| 09G2S | GOST (Russia/CIS) | Near | The usual counterpart: 345 MPa yield against 355 at the first thickness step and a 490 MPa tensile floor against 470. 09G2S is tested colder than S355J2 but reports KCU on a U-notch rather than KV on a V-notch. |
| IS 2062 E350 C | IS (India) | Near | Yield 350 MPa, quality C = impact at −20 °C. |
| SM490B | JIS (Japan) | Near | Yield 325 MPa, Rm 490–610 MPa, 27 J at 0 °C (not −20 °C); SM490YB is closer on yield (365 MPa). |
| S355J2W | EN (European) | Functional | Same mechanical properties without the weathering alloying — use where the steel is painted or galvanized. |
| S355MC | EN (European) | Functional | Normalized/as-rolled structural steel of the same yield; heavier chemistry (C ≤ 0.22), larger bend radii, chosen for plate and sections rather than cold-formed parts. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
