Certification & Material Traceability — What You Receive
Every shipment is accompanied by:
EN 10204 3.1 MTC: Original melt heat number, full chemistry (Ni 30.0–35.0%, Cr 19.0–23.0%, Fe ≥ 39.5%, C 0.06–0.10%, Al 0.25–0.60%, Ti 0.25–0.60%, Al+Ti 0.85–1.20%), room-temp. tensile (Rm ≥ 450 MPa, Rp0.2 ≥ 170 MPa, A ≥ 30%), solution anneal temperature, and grain size (≥ ASTM No. 5).
EN 10204 3.2 (on request): Issued with independent inspection by SGS / TÜV / BV / DNV per client PO.
PMI Report: XRF or OES verification per bundle / lot, confirming UNS N08811 chemistry before loading.
Heat Number Matching: Each piece/package physically tagged with the same heat number shown on the MTC; cut sub-pieces re-tagged and cross-referenced on the delivery note.
Additional Docs: Commercial Invoice, Packing List, Certificate of Origin (CCPIT), optional REACH SVHC declaration (< 0.1%) for EU shipments.
Export Packing, Incoterms & Shipping Support
Plates: VCI paper interleaved, edge-protected, strapped on plywood pallets, shrink-wrapped.
Bars: Bundle-strapped, end-capped, anti-rust coated for long transit; tag showing heat number on each bundle.
Seamless Pipes: End caps + hexagonal steel strapping + woven sleeve or plywood crate; beveled ends protected.
All Packages: Stencil-marked with PO#, heat number, dims, net/gross weight, and "KEEP DRY / FRAGILE".
Incoterms Supported: EXW Shanghai, FOB Shanghai, CIF / CFR to your port of discharge, DAP (where carrier network permits).
Coordination: We work with your nominated forwarder or recommend reliable freight partners for LCL, FCL (20'/40'), and air freight; assist with HS code advisory and customs paperwork review.
Typical Export Destinations & Project Types
???????? European Union: Refinery turnaround spares, chemical plant heat exchangers — full EN 10204 3.1 / 3.2, REACH declaration, often dual-certified 800H/800HT.
???????? USA: Ethylene cracker MRO stock, alloy verification (PMI) emphasized, ASME SA/ASTM B-series referenced on certs.
???? Middle East (UAE / Saudi / Qatar): SABER / COC coordination for fabricated items; raw alloy cleared with MTC + CO + Invoice; Arabic translation of packing list available on request.
???? Southeast Asia: Petrochemical & power plant new-builds — container-load project shipments with third-party inspection.
Why Global Buyers Choose Shanghai COCESS as Their N08811 Exporter
Traceability Guarantee: No "typical value only" MTCs — actual heat analysis and tensile values from the melt are provided.
Stock Readiness: Common sizes of plate, bar, and tube held in Shanghai warehouse — short lead vs. mill 8–12 week rolling schedules.
Technical Backup: Our metallurgy staff assist with grade clarification (800 vs. 800H vs. 800HT), drawing review for cut-layout optimization, and welding consumable recommendation (ERNiCr-3).
Transparent Pricing: Itemized quotation covering base material, cutting/machining, NDT, and export packing — no hidden charges.
Proven Export Record: Regular shipments to EU, USA, Middle East, and Asia with positive feedback on documentation accuracy and on-time delivery.
