Manufactured and inspected to GB/T 3280 (cold-rolled sheet & strip), GB/T 4237 (hot-rolled sheet) and GB/T 14976 (seamless tube), with an old-to-new designation cross-reference table.

What You Can Expect
- Old & New Designations on the Certificate: 06Cr19Ni10 = formerly 0Cr18Ni9 = ASTM 304. All three are printed side by side, so customs and design institutes don't have 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) arranged before loading.
FAQ
Chemically they are equivalent and interchangeable. The difference is the standard of judgment: GB/T 3280 vs ASTM A240. We print both designations on the certificate so neither customs nor drawing review rejects the shipment.
We take the stricter value of each element (usually carbon content and mechanical properties) and list both standard numbers on the certificate, so one shipment passes both markets.
