2205 equivalent grades: ASTM, EN, JIS, GB, DIN
2205 is ferritic-austenitic (duplex) stainless steel specified in ASTM A240. Every grade in the database that can stand in for it is listed below, drawn from 6 standard systems, each with the reason it does or does not match exactly. The full 2205 data sheet carries the composition and mechanical tables.
Last updated
2205 is cross-certified with 318S13, 1.4462, 022Cr23Ni5Mo3N and 1 more: the composition windows overlap closely enough that one certificate satisfies the other. 03Kh22N5AM3 differs on one limit only — a carbon ceiling, an impact temperature or a strength minimum. 2304 (S32304 / 1.4362), 2507 (S32750 / 1.4410), 316L and 1 more serve the same purpose without being the same steel, so a substitution there needs the design re-checked rather than the certificate. Across systems that is 1 in BS (superseded British), 1 in EN (European), 1 in GB/T (China), 1 in JIS (Japan), 1 in GOST (Russia/CIS), 4 in AISI / SAE.
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| 318S13 | BS (superseded British) | Identical | BS 1449 318S13 (withdrawn). |
| 1.4462 | EN (European) | Identical | X2CrNiMoN22-5-3: EN window covers both S31803 and S32205; modern 1.4462 plate is dual-certified S32205. |
| 022Cr23Ni5Mo3N | GB/T (China) | Identical | GB/T 20878 022Cr23Ni5Mo3N (formerly 00Cr22Ni5Mo3N). |
| SUS329J3L | JIS (Japan) | Identical | JIS G4304 SUS329J3L: Cr 21–24, Ni 4.5–6.5, Mo 2.5–3.5, N 0.08–0.20 (S31803 window). |
| 03Kh22N5AM3 | GOST (Russia/CIS) | Near | Russian TU/GOST R designations for 2205-type duplex; not in the classic GOST 5632 list. |
| 2304 (S32304 / 1.4362) | AISI / SAE | Functional | Lean duplex: 23 Cr, 4 Ni, no Mo, PREN ≈ 25 — cheaper, for less aggressive service. |
| 2507 (S32750 / 1.4410) | AISI / SAE | Functional | Super-duplex: 25 Cr, 7 Ni, 4 Mo, PREN ≥ 40 — for hot seawater and sour service. |
| 316L | AISI / SAE | Functional | Austenitic 316L: half the yield, PREN 24 — the grade 2205 usually replaces to save wall thickness. |
| 316 | AISI / SAE | Functional | Duplex S32205: double the yield, PREN 35 — the upgrade for warm chloride service. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.

Superseded names for 2205
- S31803 — UNS (1980s): Original 2205 designation; wider Cr/Mo/N window. Still valid; most material meets both.
- F51 / F60 — ASTM A182: Forging grades: F51 = S31803, F60 = S32205.
- 1.4462 / X2CrNiMoN22-5-3 — EN 10088: European designation.
- SAF 2205 — Sandvik trade name: Origin of the generic name; Uranus 45N, Avesta 2205, Outokumpu 2205 are equivalents.
- CD3MN / 4A — ACI / ASTM A890, A995: Cast equivalents.
