Shanghai COCESS Special Alloys Co., Ltd. (Shanghai Kesaishi Special Alloy) is a professional supplier and exporter of Monel K‑500 (UNS N05500 / W.Nr. 2.4375 / AMS 4676)​ round bar, forged rod, disc/ring blanks and custom forgings for marine, offshore, oilfield tool and chemical process applications. All material is sourced from qualified mills, fully traceable, and supplied in solution‑annealed (ST) or solution‑annealed + age‑hardened (STA)​ condition per ASTM B865 / ASME SB865, with EN 10204 3.1 Mill Test Certificates as standard and 3.2 with third‑party inspection (SGS / TÜV / BV / DNV) available on request. We support global shipment — EXW Shanghai, FOB Shanghai, CIF/CFR to your discharge port, or DAP where permitted — with full export documentation and seaworthy packing.

ASTM B127 / B164 / B165

Heat Treatment Conditions Supplied:

  • Solution Treated (ST):​ 980–1040°C × soak → water quench. Soft (Rp0.2 ≈ 275–380 MPa), near non‑magnetic — for customers performing in‑house aging after machining.

  • Solution Treated + Aged (STA):​ ST + 580–600°C × 8–16 h air cool → Rp0.2 ≥ 690 MPa (100 ksi grade), Rm ≥ 965 MPa, hardness 27–35 HRC — ready for installation. 110 ksi (≥758 MPa YS) grade available by selected heat / mill arrangement.


Certification & Quality Assurance — What You Receive

Every shipment is accompanied by full traceability documents:

  • EN 10204 3.1 MTC (standard):

    • Heat / Cast Number — physically tagged / stamped on each bar or forging, cross‑referenced on delivery note.

    • Full Melt Chemistry (Ni 63–70%, Cu Bal., Al 2.30–3.15%, Ti 0.35–0.85%, Fe ≤ 2.0%, C ≤ 0.25%, etc.) — actual values, not "typical range".

    • Mechanical Test Results — tensile (Rm ≥ 965 MPa), yield (Rp0.2 ≥ 690 MPa or ≥ 758 MPa if 110 ksi grade), elongation (≥ 15%), charpy impact if specified (typically @ −46°C / −73°C).

    • Heat Treatment Record — solution anneal temperature/time + aging temperature/time (for ST+Aged condition).

    • Grain Size / Surface Condition remark.

  • EN 10204 3.2 (on request):​ Signed/witnessed by appointed TPI agency (SGS / TÜV / BV / DNV).

  • PMI Verification:​ XRF or OES spot check before despatch confirming Ni≈65%, Cu≈30%, Al+Ti present — guards against mix‑up with Monel 400 or stainless grades.

  • UT Report:​ ASTM A388 Class A/B, typically Grade II recording for bars/forgings ≥ 50 mm dia. (or per PO).

  • Additional Export Docs:​ Commercial Invoice, Packing List, Certificate of Origin (CCPIT), magnetic permeability test report if specified for ST non‑mag condition.


Export Packing, Incoterms & Lead Time

  • Bars:​ Hex‑strapped bundle, end‑capped, anti‑rust coated, tag showing heat number; VCI paper wrap + woven sleeve or plywood crate.

  • Forgings / Discs:​ Individual bubble wrap + plywood case / steel‑banded wooden crate with skid; stencil‑marked PO#, heat number, dims, net/gross weight, "KEEP DRY / FRAGILE".

  • Incoterms Supported:​ EXW Shanghai, FOB Shanghai, CIF / CFR to your port, DAP (carrier network permitting).

  • Lead Time (typical from Shanghai stock):

    • Stock bar in ST or ST+Aged — 3–7 working days ex‑warehouse (cut‑to‑length / PMI / UT adds 1–2 days).

    • Custom forging from stock billet — 10–20 working days (drawing review → die/prep → forge → HT → UT → finish).

    • Mill order (non‑stock size) — advised per inquiry (typically 4–8 weeks).

  • We coordinate 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

  • ???????? USA / ???????? Canada:​ Oilfield tool shops — ST or ST+Aged K‑500 bar for MWD/LWD tool bodies, lock mandrels; full MTC + UT + mag‑perm test (ST cond.); AMS 4676 cross‑reference provided.

  • ???????? EU (Germany / Netherlands / Norway):​ Offshore supplier — seawater pump shaft blanks, valve stem stock; EN 10204 3.1 / 3.2, REACH SVHC declaration (< 0.1%), CE mark advisory if needed.

  • ???????? Australia / SE Asia:​ Marine / Navy repair yard — propeller shaft sleeve blanks, non‑mag fastener stock; PMI + MTC + CO.

  • ???????? Middle East (UAE / Saudi):​ Process plant MRO — agitator shaft blanks in sour‑trace environment (low H₂S, per ISO 15156 review); hardness cap (≤35 HRC) noted on MTC.


Why Global Buyers Choose Shanghai COCESS as Their Monel K‑500 Supplier

  • Condition Clarity:​ Explicit supply of ST (for in‑house aging) or ST+Aged (with certified ≥690 MPa YS) — no ambiguity on heat treatment status.

  • Traceability Guarantee:​ Actual melt analysis + actual tensile values on MTC — no "typical only" certificates.

  • Stock Readiness:​ Common diameters (Φ12–200 mm) of bar and forging billet held in Shanghai warehouse — short lead vs. mill 8–12 week rolling schedules.

  • Technical Backup:​ Assistance with age‑hardening temperature/time recommendation, non‑mag (ST) vs. aged selection for tool designers, weld filler advice (ERNiCu‑7 / AWS A5.14).

  • Transparent Export Pricing:​ Itemized quote covering base material, cutting/machining, UT/PMI, export packing — no hidden charges.
