GB/T Stainless Steel Standards (China & General Export)
Manufactured and inspected to GB/T 3280 (cold-rolled sheet and strip), GB/T 4237 (hot-rolled sheet) and GB/T 14976 (seamless tube), with an old/new grade cross-reference table.

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 don't need to re-verify.
- Thickness 0.3–60 mm, width up to 2000 mm; 2B / BA for cold-rolled, No.1 for hot-rolled, and HL / 8K / embossed patterns 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 shipment.
Frequently Asked Questions
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 neither customs nor drawing review will reject the shipment.
We take the stricter value for each element (usually carbon content and mechanical properties) and show both standard numbers on the certificate, so a single shipment clears both markets.
