S355JR equivalent grades: ASTM, EN, JIS, GB, DIN
S355JR is non-alloy hot-rolled structural steel specified in EN 10025-2. Substitutes are collected here from 7 standard systems; the grading column says whether a certificate covers the swap or an engineer has to. The full S355JR data sheet carries the composition and mechanical tables.

A572 Grade 50, A992, St52-3 and 6 more differ by one requirement, which is a line on the order rather than a redesign. Functionally interchangeable, S275JR, S350GD serve a different route to the same duty — check the design, not the analysis. The cross-reference below covers 2 in ASTM / ASME, 1 in DIN (superseded German), 3 in EN (European), 2 in GB/T (China), 1 in GOST (Russia/CIS), 1 in IS (India), 1 in JIS (Japan).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| A572 Grade 50 | ASTM / ASME | Near | Yield 345 MPa (50 ksi), Rm 450 MPa min; HSLA with Nb/V, no impact requirement unless supplementary S5 is ordered. |
| A992 | ASTM / ASME | Near | Yield 345–450 MPa, Rm 450 MPa min; shapes only, with a yield/tensile ratio cap of 0.85. |
| St52-3 | DIN (superseded German) | Near | Successor of St52-3 U (impact at +20 °C). |
| S355J2 | EN (European) | Near | Same strength; impact at −20 °C, P/S ≤ 0.025 %, fully killed. |
| Q355 | GB/T (China) | Near | GB/T 1591 Q355B: yield 355 MPa, Rm 470–630 MPa, 34 J at +20 °C — the direct successor of Q345B and the closest Chinese match. |
| Q355 | GB/T (China) | Near | Q355B is the counterpart: same 355 MPa yield to 16 mm, same 470–630 MPa tensile band, both tested at +20 °C. Q355B is tested to 34 J against 27 J, and allows carbon to 0.24 % against 0.24 % for S355JR in thick product — the closest cross-system match in the structural range. |
| 09G2S | GOST (Russia/CIS) | Near | GOST 19281 09G2S: yield 325–345 MPa, Rm 470–490 MPa; low-alloy Mn-Si steel, better cold toughness. |
| IS 2062 E350 BR | IS (India) | Near | Yield 350 MPa, Rm 490 MPa min, room-temperature impact. |
| SM490A | JIS (Japan) | Near | JIS G3106 SM490A: yield 325 MPa (≤ 16 mm), Rm 490–610 MPa; A = no impact requirement, B = 27 J at 0 °C. |
| S275JR | EN (European) | Functional | Higher class; same delivery conditions. |
| S350GD | EN (European) | Functional | Uncoated hot-rolled equivalent by yield, for profiles hot-dip galvanized after forming. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
