St52-3 equivalent grades: ASTM, EN, JIS, GB, DIN
St52-3 is general structural steel (DIN 17100, withdrawn) — today S355J2 / S355JR specified in DIN 17100. 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 St52-3 data sheet carries the composition and mechanical tables.

For St52-3 the exact matches are S355J2, and material bought as one is accepted as the other without deviation. A572 Grade 50, 50B / 50D, S355JR and 4 more sit one step away, differ in a strength minimum or in the quality class rather than in the metallurgy. The cross-reference below covers 2 in EN (European), 1 in ASTM / ASME, 1 in BS (superseded British), 1 in GB/T (China), 1 in GOST (Russia/CIS), 1 in IS (India), 1 in JIS (Japan).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 |
|---|---|---|---|
| S355J2 | EN (European) | Identical | Successor of St52-3 N (1.0577); same yield table, tensile 470–630 MPa, 27 J at −20 °C, cleaner P/S. |
| A572 Grade 50 | ASTM / ASME | Near | Yield 345 MPa, Rm 450 MPa min; HSLA — the usual US replacement on St52 drawings. |
| 50B / 50D | BS (superseded British) | Near | BS 4360 50B (+20 °C) and 50D (−20 °C). |
| S355JR | EN (European) | Near | Successor of St52-3 U (impact at +20 °C). |
| Q355B / Q345B | GB/T (China) | Near | GB/T 1591 Q355B (355 MPa, 470–630 MPa) — formerly Q345B; commonly quoted as the Chinese St52. |
| 09G2S / 17GS | GOST (Russia/CIS) | Near | GOST 19281 09G2S (yield 325–345 MPa) and 17GS (yield 345 MPa) are the CIS 'St52' equivalents. |
| IS 2062 E350 | IS (India) | Near | Yield 350 MPa, Rm 490 MPa min. |
| SM490B / SM490YB | JIS (Japan) | Near | JIS G3106 SM490B: yield 325 MPa, Rm 490–610 MPa, 27 J at 0 °C; SM490YB yield 365 MPa. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
