cross reference · GB/T 20878 · UNS · JIS · 304 · 316L

The same material is written differently across standards. 304 is 06Cr19Ni10 in GB, 1.4301 in EN, S30400/304 in UNS/ASTM and SUS304 in JIS; chemistry and properties govern acceptance.

Stainless grades are designated differently in GB/T 20878, EN 10088, ASTM/UNS and JIS. Common equivalents:

| Family | GB | EN | UNS/ASTM | JIS |
|---|---|---|---|---|
| 304 | 06Cr19Ni10 | 1.4301 | S30400 / 304 | SUS304 |
| 304L | 022Cr19Ni10 | 1.4306/1.4307 | S30403 / 304L | SUS304L |
| 316L | 022Cr17Ni12Mo2 | 1.4404 | S31603 / 316L | SUS316L |
| 316Ti | 06Cr17Ni12Mo2Ti | 1.4571 | S31635 / 316Ti | SUS316Ti |
| 321 | 06Cr18Ni11Ti | 1.4541 | S32100 / 321 | SUS321 |
| 2205 | 022Cr23Ni5Mo3N | 1.4462 | S32205 / 2205 | SUS329J3L |
| 430 | 10Cr17 | 1.4016 | S43000 / 430 | SUS430 |

Cautions:

1) The table is for communication, not automatic substitution; C, Ni and Mo ranges and permitted deviations differ between systems.
2) Some "close" grades (e.g. 1.4306 vs 304L) have different minimum chemistry — important for deep drawing or welded parts.
3) Quotes and mill certificates should state both system and grade designation, e.g. "316L, UNS S31603, per ASTM A240".

A cross-reference answers "is it the same steel"; conformance still depends on the contract standard and measured values.
