S355J2W equivalent grades: ASTM, EN, JIS, GB, DIN
S355J2W is weathering (atmospheric-corrosion-resistant) structural steel, −20 °C impact specified in EN 10025-5. What follows is the substitution list: 5 standard systems, and for each candidate the clause that makes it an exact match or stops it being one. The full S355J2W data sheet carries the composition and mechanical tables.
Last updated
A588 Grade A / B, S235J2W, Q355NH and 2 more sit one step away, differ in a strength minimum or in the quality class rather than in the metallurgy. A242 Type 1, A606 Type 4, S355J2 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: 3 in ASTM / ASME, 2 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 |
|---|---|---|---|
| A588 Grade A / B | ASTM / ASME | Near | ASTM A588: 345 MPa yield, 485 MPa tensile, Cu-Cr-Ni(-V) weathering steel for bridges — the US Corten B; Grade A is Cr-rich, Grade B Ni-rich, both within S355J2W chemistry ranges. |
| S235J2W | EN (European) | Near | Lower-strength weathering grade (235 MPa) for façades and non-critical members. |
| Q355NH | GB/T (China) | Near | GB/T 4171 weathering structural steel, 355 MPa yield; Q355NH (Cu-Cr-Ni) ≈ S355J2W, Q355GNH ≈ WP type. |
| 10ХНДП / 14ХГНДЦ | GOST (Russia/CIS) | Near | GOST 19281 weathering (Cu-Ni-P and Cu-Cr-Ni) structural steels of 345–355 MPa class. |
| SMA490BW / CW | JIS (Japan) | Near | JIS G3114 welded structural weathering steel, 355 MPa yield (≤ 16 mm), 490–610 MPa tensile; B = 0 °C, C = −5 °C impact. |
| A242 Type 1 | ASTM / ASME | Functional | ASTM A242: the original Cu-P weathering steel (345 MPa ≤ 19 mm) — closer to S355J2WP; used for sheet and light sections. |
| A606 Type 4 | ASTM / ASME | Functional | ASTM A606 Type 4 sheet and strip with enhanced corrosion resistance (345 MPa) — the thin-gauge façade equivalent. |
| S355J2 | EN (European) | Functional | Same mechanical properties without the weathering alloying — use where the steel is painted or galvanized. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
