1.4404 equivalent grades: ASTM, EN, JIS, GB, DIN
1.4404 is austenitic Cr-Ni-Mo stainless steel, low carbon specified in EN 10088-2. Substitutes are collected here from 6 standard systems; the grading column says whether a certificate covers the swap or an engineer has to. The full 1.4404 data sheet carries the composition and mechanical tables.
Last updated
1.4404 is cross-certified with 316L, 316S11, 022Cr17Ni12Mo2 and 1 more: the composition windows overlap closely enough that one certificate satisfies the other. A single clause separates 316, 1.4401, 1.4571 and 2 more: differ either a test temperature or a composition bound that the other does not. Functionally interchangeable, 1.4301, 1.4462 serve a different route to the same duty — check the design, not the analysis. The table holds 2 in AISI / SAE, 1 in BS (superseded British), 1 in GB/T (China), 1 in JIS (Japan), 5 in EN (European), 1 in GOST (Russia/CIS).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| 316L | AISI / SAE | Identical | UNS S31603 (ASTM A240): C ≤ 0.03, Cr 16–18, Ni 10–14, Mo 2–3; 1.4404 sits inside the 316L window and is dual-certified. |
| 316S11 | BS (superseded British) | Identical | BS 1449 316S11: C ≤ 0.03, Cr 16.5–18.5, Ni 10–13, Mo 2–2.5. |
| 022Cr17Ni12Mo2 | GB/T (China) | Identical | GB/T 20878 022Cr17Ni12Mo2 (formerly 00Cr17Ni14Mo2). |
| SUS316L | JIS (Japan) | Identical | JIS G4304 SUS316L: C ≤ 0.03, Cr 16–18, Ni 12–15, Mo 2–3. |
| 316 | AISI / SAE | Near | S31600 allows C ≤ 0.08; 1.4401 is the EN counterpart. 1.4404 meets 316 mechanicals only at the low end (316 requires Rp0.2 ≥ 205 MPa — satisfied). |
| 1.4401 | EN (European) | Near | X5CrNiMo17-12-2 (316): C ≤ 0.07; higher strength minimums (Rp0.2 ≥ 240 MPa plate). |
| 1.4571 | EN (European) | Near | X6CrNiMoTi17-12-2 (316Ti): Ti-stabilized instead of low-carbon; same corrosion class, slightly higher strength, poorer polish. |
| 1.4432 / 1.4436 | EN (European) | Near | 2.5–3.0 % Mo versions (316L high-Mo) for slightly higher PREN. |
| 03Kh17N14M3 | GOST (Russia/CIS) | Near | GOST 5632 03Kh17N14M3: C ≤ 0.03, Mo 2.5–3.0, Ni 13–15 — richer than 1.4404. |
| 1.4301 | EN (European) | Functional | Non-Mo 304: cheaper, lower pitting resistance. |
| 1.4462 | EN (European) | Functional | Austenitic 316L: half the yield strength, PREN 24; the grade 1.4462 usually replaces. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
