Direct Factory Supply Incoloy 800HT Alloy | Competitive Price & Fast Delivery

Shanghai COCESS Special Alloys Co., Ltd. (Shanghai Kesaishi Special Alloy) supplies Incoloy 800HT (UNS N08811 / W.Nr. 1.4959 / X8NiCrAlTi32-21)​ directly from warehouse stock—eliminating multiple trading markups while keeping full mill traceability. All material is solution-annealed per ASTM requirements (≥1149°C soak, water-quenched or rapidly air-cooled), with EN 10204 3.1 MTC stating C ≥ 0.06%, Al+Ti ≥ 0.85%, grain size ≥ ASTM 5, and heat number clearly marked on every piece. We support cut-to-size, beveling, UT/PMI, third-party inspection (SGS / TÜV / BV / DNV), and container-load or LCL shipments worldwide for ethylene cracker radiant tubes, SMR catalyst tubes, high-temp furnace components, and creep-critical pressure equipment.

What We Keep in Stock — Incoloy 800HT (UNS N08811)

Dual-certified 800H/800HT (N08810 + N08811)​ material is also available—meeting C ≥ 0.05%, Al+Ti ≥ 0.85%, coarse grain ≥ ASTM 5—suitable when project specs reference either grade.

Why "Direct Factory Supply + Warehouse Stock" Saves You Money & Time

• No Trader Markup:​ We source directly from qualified Chinese specialty mills (some imported billet/plate as reference) and hold stock in our Shanghai warehouse—you pay close to replacement cost, not layered resale margins.

• Fast Release vs. Mill Lead Time:​ Mill-made Incoloy 800HT often quotes 8–14 weeks; our stock items can be released within 24–48 hours​ after order confirmation (same-day for urgent collect). Cutting, beveling, and PMI can be done before crating.

• Transparent Quotation:​ Firm price valid 3–7 days (or locked per LME-nickel formula if agreed), itemized for material, cutting, NDT, and seaworthy packing—no hidden fees.

• Volume Flexibility:​ From one plate cut-to-size / one bar length for shutdown spares → to multi-ton project lots → to annual frame agreement with quarterly price review.

Quality Assurance — Same as Mill-Delivered Material

• MTC:​ EN 10204 3.1 as standard; EN 10204 3.2 with surveyor witness arranged on request.

• Chemistry & Grain:​ MTC shows full melt analysis (Ni 30–35%, Cr 19–23%, C ≥ 0.06%, Al+Ti 0.85–1.20%), tensile results (Rm ≥ 450 MPa, Rp0.2 ≥ 170 MPa, A ≥ 30%), solution anneal temperature, and grain size ≥ ASTM 5.

• PMI Check:​ 100% XRF/OES verification before shipment; report issued per lot.

• NDT Options:​ UT per ASTM A388 (bars/forgings, Class A/B, usually Grade II), ET per ASTM E426 or hydrostatic (tubes), PT/MT on machined surfaces if specified.

• Traceability:​ Each piece / bundle tagged with heat number matching MTC; sub-piece tagging provided after cutting.

Value-Added Services Available In-House

• Plate:​ CNC plasma / laser / waterjet cutting to shape, hole drilling, edge chamfering, flattening, layout optimization to reduce offcut.

• Bar:​ Saw cut to length, turning / grinding to h9/h11, rough machining of steps or center holes per sketch.

• Pipe / Tube:​ End beveling (30°/37.5°), U-bending for heat exchangers, inner polishing (Ra ≤ 0.8 µm on request), cap & tag.

• Packaging:​ VCI interleaved plates on plywood pallets; bundled pipes/bars with end caps + hex-strapping + woven wrap; export crate for airfreight / LCL.

Typical Applications of Our Incoloy 800HT Stock

• Ethylene pyrolysis (cracker) furnace radiant tubes​ (800–950°C, carburizing atmosphere)

• Steam Methane Reformer (SMR)​ catalyst tubes & outlet pigtails / manifolds

• Secondary reformer transition sections (ammonia / hydrogen plants)

• High-temp carburizing / nitro-carburizing furnace muffles, hangers, radiant screens

• Creep-critical pressure piping > 760°C where N08800/N08810 are insufficient
