1.4301 equivalent grades: ASTM, EN, JIS, GB, DIN
1.4301 is austenitic Cr-Ni stainless steel specified in EN 10088-2. 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 1.4301 data sheet carries the composition and mechanical tables.
Last updated
Where a drawing says 1.4301, 304, 304S31, 06Cr19Ni10 and 2 more satisfies it as written, with no concession needed. 304L, 1.4307 differ by one requirement, which is a line on the order rather than a redesign. Functionally interchangeable, 1.4404, 1.4305 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 The table holds 2 in AISI / SAE, 1 in BS (superseded British), 1 in GB/T (China), 1 in GOST (Russia/CIS), 1 in JIS (Japan), 3 in EN (European).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| 304 | AISI / SAE | Identical | AISI 304 / UNS S30400 (ASTM A240): same Cr/Ni window; C ≤ 0.08 vs 0.07, S ≤ 0.030 vs 0.015. Dual-certified 1.4301/304 is the norm. |
| 304S31 | BS (superseded British) | Identical | BS 1449 304S31: C ≤ 0.07, Cr 17–19, Ni 8–11. |
| 06Cr19Ni10 | GB/T (China) | Identical | GB/T 20878 06Cr19Ni10 (formerly 0Cr18Ni9): C ≤ 0.08, Cr 18.0–20.0, Ni 8.0–11.0. |
| 08Kh18N10 | GOST (Russia/CIS) | Identical | GOST 5632 08Kh18N10: C ≤ 0.08, Cr 17–19, Ni 9–11. |
| SUS304 | JIS (Japan) | Identical | JIS G4304/G4305 SUS304: C ≤ 0.08, Cr 18.0–20.0, Ni 8.0–10.5. |
| 304L | AISI / SAE | Near | UNS S30403: C ≤ 0.03 — the low-carbon version; EN equivalent is 1.4307 (X2CrNi18-9). |
| 1.4307 | EN (European) | Near | X2CrNi18-9, C ≤ 0.03 — the low-carbon variant for welded heavy sections (304L). |
| 1.4404 | EN (European) | Functional | X2CrNiMo17-12-2 (316L) with 2 % Mo: substitute when chloride pitting resistance is needed. |
| 1.4305 | EN (European) | Functional | Non-free-machining base grade: better corrosion resistance and weldability, poorer machinability. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
