1.4404 equivalent grades: ASTM, EN, JIS, GB, DIN

Cross-reference for 1.4404 across standard systems. Each match is graded so you can see how safe the substitution is. Austenitic Cr-Ni-Mo stainless steel, low carbon — full 1.4404 data sheet.

Cross-reference table

Identical = same composition and mechanical limits within rounding. Near = one limit differs (e.g. carbon max or impact temperature). Functional = interchangeable for most uses after an engineering check.

How the matches are graded

Identical means the chemical composition windows overlap so that material certified to one specification meets the other without deviation, and the mechanical minimums are the same or the other is inside them — mills usually dual-certify. Near means one limit differs (a carbon maximum, an impact temperature, a strength minimum or a delivery condition) and a substitution needs a one-line engineering check. Functional means the grades serve the same purpose but are not the same steel — a designer can often use one for the other, but only after re-checking the design.

1.4404 in AISI / SAE

• 316L — 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.
• 316 — 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).

1.4404 in BS (superseded British)

• 316S11 — Identical BS 1449 316S11: C ≤ 0.03, Cr 16.5–18.5, Ni 10–13, Mo 2–2.5.

1.4404 in GB/T (China)

• 022Cr17Ni12Mo2 — Identical GB/T 20878 022Cr17Ni12Mo2 (formerly 00Cr17Ni14Mo2).

1.4404 in JIS (Japan)

• SUS316L — Identical JIS G4304 SUS316L: C ≤ 0.03, Cr 16–18, Ni 12–15, Mo 2–3.

1.4404 in EN (European)

• 1.4401 — Near X5CrNiMo17-12-2 (316): C ≤ 0.07; higher strength minimums (Rp0.2 ≥ 240 MPa plate).
• 1.4571 — Near X6CrNiMoTi17-12-2 (316Ti): Ti-stabilized instead of low-carbon; same corrosion class, slightly higher strength, poorer polish.
• 1.4432 / 1.4436 — Near 2.5–3.0 % Mo versions (316L high-Mo) for slightly higher PREN.
• 1.4301 — Functional Non-Mo 304: cheaper, lower pitting resistance.
• 1.4462 — Functional Austenitic 316L: half the yield strength, PREN 24; the grade 1.4462 usually replaces.

1.4404 in GOST (Russia/CIS)

• 03Kh17N14M3 — Near GOST 5632 03Kh17N14M3: C ≤ 0.03, Mo 2.5–3.0, Ni 13–15 — richer than 1.4404.

Superseded names for 1.4404

• X2CrNiMo17 13 2 — DIN 17440 (withdrawn): Same number 1.4404; name changed to 17-12-2 in EN 10088.
• V4A — Krupp trade name: German colloquial name for the Mo-bearing austenitics (1.4401, 1.4404, 1.4571).
• 316S11 — BS 1449 / BS 970
• Z3CND17-12-02 — NF A 35-573
