GB/T 4237 · ASTM A240 · EN 10088-2 · cross reference

All three standards cover hot-rolled stainless plate, but grade designations, chemistry ranges and inspection rules differ. The cross-reference helps locate equivalents; verify chemistry and properties before substitution.

Hot-rolled stainless plate purchasing commonly involves GB/T 4237, ASTM A240 and EN 10088-2. Their relationship:

| Item | GB/T 4237 | ASTM A240 | EN 10088-2 |
|---|---|---|---|
| Scope | Hot-rolled stainless plate/wide sheet | Chromium-nickel stainless plate/sheet | Stainless flat products (corrosion-resistant) |
| Grade notation | 06Cr19Ni10 etc. | 304/304L, 316L etc. | 1.4301, 1.4404 etc. |
| Chemistry | Chinese national ranges | ASTM ranges (some elements wider) | EN ranges with permitted deviations |
| Mechanicals | GB guaranteed values | ASTM guaranteed values | EN guaranteed values |

Common correspondences (verify per heat):

• 06Cr19Ni10 ≈ 304 ≈ 1.4301
• 022Cr19Ni10 ≈ 304L ≈ 1.4306/1.4307
• 022Cr17Ni12Mo2 ≈ 316L ≈ 1.4404
• 06Cr17Ni12Mo2Ti ≈ 316Ti ≈ 1.4571
• 022Cr23Ni5Mo3N ≈ 2205 ≈ 1.4462

Practical advice:

1) State the standard and grade notation in the contract to avoid "produced to GB, inspected to ASTM" mismatches.
2) When dual certification is required, verify that the chemistry and mechanicals satisfy both standards.
3) Cross-reference tables locate candidates only — the contract standard and measured data govern acceptance.
