410 equivalent grades: ASTM, EN, JIS, GB, DIN
410 is martensitic chromium stainless steel, hardenable specified in ASTM A276. 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 410 data sheet carries the composition and mechanical tables.

410 is cross-certified with 410S21, 1.4006, 12Cr13 and 2 more: the composition windows overlap closely enough that one certificate satisfies the other. 420, 416, 410S differ on one limit only — a carbon ceiling, an impact temperature or a strength minimum. 430, 17-4 PH 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 Across systems that is 1 in BS (superseded British), 1 in EN (European), 1 in GB/T (China), 1 in GOST (Russia/CIS), 1 in JIS (Japan), 5 in AISI / SAE.
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| 410S21 | BS (superseded British) | Identical | BS 970 410S21: C 0.09–0.15, Cr 11.5–13.5. |
| 1.4006 | EN (European) | Identical | X12Cr13: C 0.08–0.15, Cr 11.5–13.5 — same steel with a carbon minimum; dual-certified. |
| 12Cr13 | GB/T (China) | Identical | GB/T 20878 12Cr13 (formerly 1Cr13). |
| 12Kh13 | GOST (Russia/CIS) | Identical | GOST 5632 12Kh13: C 0.09–0.15, Cr 12–14. |
| SUS410 | JIS (Japan) | Identical | JIS G4303 SUS410: C ≤ 0.15, Cr 11.5–13.5. |
| 420 | AISI / SAE | Near | S42000 / 1.4021: C ≥ 0.15 (typically 0.20–0.40) → 48–55 HRC; the cutlery and mould grade. |
| 416 | AISI / SAE | Near | S41600 / 1.4005: free-machining 410 with 0.15 % S min. |
| 410S | AISI / SAE | Near | S41008 / 1.4000: C ≤ 0.08, does not harden on welding — for annealed plate and clad. |
| 430 | AISI / SAE | Functional | Ferritic 17 % Cr: better corrosion resistance, not hardenable. |
| 17-4 PH | AISI / SAE | Functional | Conventional martensitic 12 % Cr: cheaper, lower strength (≤ 1200 MPa), poorer corrosion resistance, needs quench hardening. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
