Discover the latest trends and innovations in the nickel alloy industry. We provide expert insights and in-depth analysis on the newest developments in nickel alloys.
Inconel 625 (UNS N06625 / W.Nr. 2.4856) is a nickel-chromium-molybdenum superalloy stabilized with niobium, widely recognized for its exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, alongside reliable strength from cryogenic temperatures up to 980°C. As a dedicated stockist, Shanghai COCESS Special Alloys Co., Ltd maintains a large, ready-to-ship inventory of Inconel 625 Sheet, Plate, Bar, and Tube, while offering precision custom sizing services to meet urgent project timelines without compromising on ASTM standard compliance.
Precise Chemical Composition & Mechanical Baseline
The reliability of our stock originates from strictly controlled chemistry, ensuring consistent solid-solution strengthening and corrosion immunity across all inventory batches:
Chemical Composition (wt.%): Ni ≥ 58.0 (Balance), Cr 20.0 – 23.0, Mo 8.0 – 10.0, Nb+Ta 3.15 – 4.15, Fe ≤ 5.0, C ≤ 0.10 (High-quality stock often sourced with C ≤ 0.03~0.05 for enhanced purity), Mn ≤ 0.50, Si ≤ 0.50, Al ≤ 0.40, Ti ≤ 0.40. The high Mo and Nb content ensure a Pitting Resistance Equivalent Number (PREN) > 45.
Mechanical Properties (Annealed / Solution Treated, Room Temp):
Tensile Strength (Rm): ≥ 830 MPa (Typical 827–965 MPa).
Yield Strength (Rp0.2): ≥ 414 MPa (Typical 414–552 MPa).
Elongation (A): ≥ 30% (Typical 30–50%), guaranteeing high toughness for formed parts.
Physical Data: Density 8.44 g/cm³; Melting Range 1290 – 1350°C; Non-magnetic.
Large Inventory: Standard Stock Sizes
Shanghai COCESS Special Alloys Co., Ltd holds extensive stock across key product forms, adhering to ASTM B443, B446, and B444 dimensions, enabling rapid dispatch for emergency maintenance or production runs:
Sheet & Plate (ASTM B443):
Cold Rolled Sheet/Coil: Thickness 0.5mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm (Range approx. 0.5–6.0mm), Standard Widths 1000mm, 1219mm, 1500mm.
Hot Rolled Plate: Thickness 6.0mm, 10.0mm, 12.0mm, 15.0mm, 20.0mm, 25.0mm, 50.0mm (Range approx. 6.0–100mm+), Standard 1500x6000mm or 2000x6000mm.
Bar & Rod (ASTM B446):
Cold Drawn/Precision: Diameter Ø10mm, Ø20mm, Ø30mm, Ø50mm (Range approx. Ø2–80mm), Bright/Peeled finish.
Hot Rolled/Forged: Diameter Ø60mm, Ø100mm, Ø150mm, Ø200mm, Ø250mm (Range approx. Ø20–300mm+), available Black or Turned.
Seamless Tube & Pipe (ASTM B444):
Instrument/Heat Exchanger Tubes: OD Ø6mm, Ø12mm, Ø25mm, Ø50mm, Ø100mm (Range approx. Ø6–273mm), Wall Thickness 0.5–20mm.
Common configurations like Ø25.4x2.11mm, Ø50.8x3.0mm are frequently available for immediate shipment.
Custom Sizes & Value-Added Processing
Beyond standard stock, we bridge the gap between inventory and project-specific requirements through in-house custom processing, ensuring you receive net-shape or near-net-shape materials:
Precision Cutting: Utilizing Waterjet, Plasma, or Laser cutting for plates/sheets to custom rectangular/square dimensions (e.g., cutting a 1500x6000mm plate into specific 800x1200mm workpieces) with tight tolerances, minimizing your scrap and machining time.
Bar Sawing & Machining: Cutting round bars to specific lengths (e.g., 200mm, 500mm, 1500mm multiples) or providing rough turned/machined blanks to reduce your workshop load.
Slitting & Decoiling: Custom slitting of coils to specific widths (e.g., taking 1219mm wide coil and slitting to 100mm or 300mm strips for gasket or shielding fabrication).
Lead Time Advantage: While our large inventory covers most standard calls for immediate dispatch (often within 24-48 hours for stock items), custom processed sizes are typically turned around swiftly, significantly faster than mill-direct lead times.
Quality Assurance & Industrial Application
Every item dispatched from our stock, whether standard or custom cut, is backed by an EN 10204 3.1 Material Test Certificate (MTC) ensuring full heat number traceability and compliance with the specified ASTM chemistry/mechanics.
Target Sectors: Our readily available Inconel 625 supports Marine & Offshore (seawater piping, risers), Chemical Processing (acid reactors, FGD systems), Aerospace (exhaust ducts), and Oil & Gas (sour service components).
Compliance: Materials meet NACE MR-01-75 (ISO 15156) where applicable, and we support third-party inspection (SGS, TUV, BV) for critical consignments.
