St52-3 equivalent grades: ASTM, EN, JIS, GB, DIN
Cross-reference for St52-3 across standard systems. Each match is graded so you can see how safe the substitution is. General structural steel (DIN 17100, withdrawn) — today S355J2 / S355JR — full St52-3 data sheet.
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 Gr. 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| 50B / 50D | BS (superseded British) | Near | BS 4360 50B (+20 °C) and 50D (−20 °C).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 = same composition and mechanical limits within rounding. Near = one limit differs (e.g. carbon max or impact temperature). Functional = interchangeable for most uses after an engineering check.
How the matches are graded
Identical means the chemical composition windows overlap so that material certified to one specification meets the other without deviation, and the mechanical minimums are the same or the other is inside them — mills usually dual-certify. Near means one limit differs (a carbon maximum, an impact temperature, a strength minimum or a delivery condition) and a substitution needs a one-line engineering check. Functional means the grades serve the same purpose but are not the same steel — a designer can often use one for the other, but only after re-checking the design.
