430 equivalent grades: ASTM, EN, JIS, GB, DIN
Cross-reference for 430 across standard systems. Each match is graded so you can see how safe the substitution is. Ferritic chromium stainless steel — full 430 data sheet.
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| 430S17 | BS (superseded British) | Identical | BS 1449 430S17: C ≤ 0.08, Cr 16–18. |
| 1.4016 | EN (European) | Identical | X6Cr17: C ≤ 0.08, Cr 16–18. Dual-certified 430/1.4016 sheet is standard in Europe. |
| 10Cr17 | GB/T (China) | Identical | GB/T 20878 10Cr17 (formerly 1Cr17). |
| 12Kh17 | GOST (Russia/CIS) | Identical | GOST 5632 12Kh17: C ≤ 0.12, Cr 16–18. |
| SUS430 | JIS (Japan) | Identical | JIS G4305 SUS430: C ≤ 0.12, Cr 16–18. |
| 439 / 1.4510 | AISI / SAE | Near | Ti-stabilized 17 % Cr (S43035 / X3CrTi17): weldable without sensitization, same corrosion class — the upgrade for welded parts. |
| 441 / 1.4509 | AISI / SAE | Near | Nb+Ti dual-stabilized 18 % Cr for exhaust systems and heat exchangers. |
| 409 / 1.4512 | AISI / SAE | Functional | 11 % Cr ferritic for exhausts; cheaper, lower corrosion resistance. |
| 304 | AISI / SAE | Functional | Austenitic 18-8: better corrosion resistance, formability and weldability; 430 replaces it on cost in dry indoor service. |
| 410 | AISI / SAE | Functional | Ferritic 17 % Cr: better corrosion resistance, not hardenable. |
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.
