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 — 8 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.

Where a drawing says S355J2, St52-3, S355J2H satisfies it as written, with no concession needed. A572 Grade 50, A709 Gr. 50, S355JR and 8 more sit one step away, differ in a strength minimum or in the quality class rather than in the metallurgy. S355J2W, S355MC, AR400 and 2 more serve the same purpose without being the same steel, so a substitution there needs the design re-checked rather than the certificate. Counted by system: 1 in DIN (superseded German), 6 in EN (European), 2 in ASTM / ASME, 2 in GB/T (China), 2 in GOST (Russia/CIS), 1 in IS (India), 1 in JIS (Japan), 3 in Proprietary (trade names).
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| St52-3 | DIN (superseded German) | Identical | Successor of St52-3 N (1.0577); same yield table, tensile 470–630 MPa, 27 J at −20 °C, cleaner P/S. |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). |
| E355 | EN (European) | Near | EN 10025-2 S355J2: effectively the same analysis and, in the +N condition, the same 355 MPa yield and 490–630 MPa tensile. The difference is what else each standard demands — S355J2 guarantees 27 J at −20 °C and structural tolerances, while E355 guarantees dimensional precision and surface finish and requires no impact test at all. |
| 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. |
| AR400 | Proprietary (trade names) | Functional | EN 10025-2 S355J2 at roughly 150 HBW. Listed as the benchmark: in sliding abrasion AR400 lasts about **three to four times** as long, which is the whole economic case for wear plate. S355J2 is what the surrounding structure is made of. |
| AR450 | Proprietary (trade names) | Functional | EN 10025-2 S355J2 at roughly 150 HBW — the reference point for wear calculations. AR450 lasts roughly four to five times as long in sliding abrasion. |
| AR500 | Proprietary (trade names) | Functional | EN 10025-2 S355J2 at roughly 150 HBW — the reference point. AR500 lasts about five to six times as long in sliding abrasion, and that multiplier is the whole reason to accept its fabrication penalties. |
