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

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 don't have to cross-check.
- Thickness 0.3–60 mm, width up to 2000 mm; cold-rolled 2B / BA, hot-rolled No.1, and HL / 8K / embossed for textured-surface plate.
- Certificates can be issued to GB/T, or to EN 10204 3.1 in parallel; third-party inspection (SGS / BV) is arranged before loading.
FAQ
Chemically they are equivalent and interchangeable. The difference is the assessment standard: GB/T 3280 versus ASTM A240. We print both designations on the certificate so customs or drawing review won't reject the shipment.
We take the stricter value for each element (usually carbon content and mechanical properties) and list both standard numbers on the certificate, so a single shipment passes both markets.
