GB/T Standards for Stainless Steel (China & General Export)
Manufactured and tested to GB/T 3280 (cold-rolled sheet and strip), GB/T 4237 (hot-rolled sheet) and GB/T 14976 (seamless pipe), with an old/new grade cross-reference table.
Products and the Standards We Supply To
| Product | Standard | Grades We Commonly Ship |
|---|---|---|
| Cold-Rolled Sheet / Strip | GB/T 3280 | 06Cr19Ni10 (304) / 022Cr17Ni12Mo2 (316L) / 10Cr17 (430) |
| Hot-Rolled Sheet | GB/T 4237 | 06Cr19Ni10 / 022Cr17Ni12Mo2 |
| Seamless Pipe | GB/T 14976 | 06Cr19Ni10 / 022Cr17Ni12Mo2 |
| Welded Pipe | GB/T 12771 | 06Cr19Ni10 |
| Cold-Rolled Strip | GB/T 4239 | 06Cr19Ni10 / 10Cr17 |
What You Can Expect
- Old and New Designations on the Certificate: 06Cr19Ni10 = former 0Cr18Ni9 = ASTM 304. All three are printed side by side, so customs and project institutes have nothing to cross-check.
- Thickness 0.3–60 mm, width up to 2000 mm; cold-rolled 2B / BA, hot-rolled No.1, plus HL / 8K / embossed for surface-finished sheet.
- Certificates can be issued to GB/T or in parallel to EN 10204 3.1; third-party inspection (SGS / BV) is arranged before loading.
FAQ
Chemically they are equivalent and interchangeable. The difference lies in the assessment standard: GB/T 3280 versus ASTM A240. We print both designations on the certificate so that neither customs nor drawing review rejects the shipment.
We take the stricter value for each element (usually carbon content and mechanical properties) and state both standard numbers on the certificate, so a single shipment clears both markets.
