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| 304S31 | BS (superseded British) | Identical | BS 1449 304S31: C ≤ 0.07, Cr 17–19, Ni 8–11.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. |

| 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 = 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.
