What You Can Expect
- Old and New Designations on the Certificate: 06Cr19Ni10 = formerly 0Cr18Ni9 = ASTM 304. All three are printed side by side, so customs and design institutes have no need to re-verify.
- Thickness 0.3–60 mm, width up to 2000 mm; cold-rolled 2B / BA, hot-rolled No.1, and 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 shipment.
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 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.
