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 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 surface-finished sheet in HL / 8K / embossed.
- Certificates can be issued to GB/T or, in parallel, to EN 10204 3.1; third-party inspection (SGS / BV) is arranged before loading.
Frequently Asked Questions
They are chemically 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 rejects 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 clears both markets.
