S235J0 equivalent grades: ASTM, EN, JIS, GB, DIN
S235J0 is non-alloy hot-rolled structural steel specified in EN 10025-2. Substitutes are collected here from 5 standard systems; the grading column says whether a certificate covers the swap or an engineer has to. The full S235J0 data sheet carries the composition and mechanical tables.

A36, S235JR, Q235 and 1 more sit one step away, differ in a strength minimum or in the quality class rather than in the metallurgy. Functionally interchangeable, SS400 serves a different route to the same duty — check the design, not the analysis. The cross-reference below covers 1 in ASTM / ASME, 1 in EN (European), 1 in GB/T (China), 1 in GOST (Russia/CIS), 1 in JIS (Japan).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| A36 | ASTM / ASME | Near | A36 has a higher yield (250 MPa) and no Charpy requirement at all, so it does not substitute where the 0 °C toughness is the reason for the specification. |
| S235JR | EN (European) | Near | Same chemistry ceiling and identical mechanical properties; only the impact test temperature differs (+20 °C against 0 °C) plus 0.005 % on P and S. |
| Q235 | GB/T (China) | Near | Q235C is the Chinese quality tested at 0 °C and is the closest GB/T 700 match; Q235B corresponds to S235JR. |
| St3sp | GOST (Russia/CIS) | Near | St3sp category 4 or 5 is the closer match where low-temperature testing is required — tested at −20 °C, against 0 °C for S235J0. |
| SS400 | JIS (Japan) | Functional | JIS G3101 SS400 has comparable strength but no impact requirement, so it matches S235J0 on strength only. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
S235J0 in ASTM / ASME
- A36 — Near A36 has a higher yield (250 MPa) and no Charpy requirement at all, so it does not substitute where the 0 °C toughness is the reason for the specification.
S235J0 in EN (European)
- S235JR — Near Same chemistry ceiling and identical mechanical properties; only the impact test temperature differs (+20 °C against 0 °C) plus 0.005 % on P and S.
S235J0 in GB/T (China)
- Q235 — Near Q235C is the Chinese quality tested at 0 °C and is the closest GB/T 700 match; Q235B corresponds to S235JR.
S235J0 in GOST (Russia/CIS)
- St3sp — Near St3sp category 4 or 5 is the closer match where low-temperature testing is required — tested at −20 °C, against 0 °C for S235J0.
S235J0 in JIS (Japan)
- SS400 — Functional JIS G3101 SS400 has comparable strength but no impact requirement, so it matches S235J0 on strength only.
Superseded names for S235J0
- St 37-3 U — DIN 17100 (withdrawn 1994): The unalloyed, non-normalised quality; the closest legacy German name and still seen on older drawings.
- Fe 360 C — EN 10025:1990: The pre-1993 European designation; C corresponded to the 0 °C impact class.
- E 24-3 — NF A 35-501 (France, withdrawn): French legacy designation of the same quality class.
- Fe 360 C — UNI 7070 (Italy, withdrawn): Italian legacy designation.
