ASTM B444 / UNS N06625 Inconel 625 Pipes & Tubes Manufacturer, Supplier & Exporter — Engineered for the Harshest Environments
UNS N06625 Pipes and Tubes, DIN 2.4856 Pipes and Tubes, Inconel Alloy 625 Tubing, Inconel 625 Pipes, Inconel 625 Seamless Pipes, Alloy 625 ERW Pipes, 625 Inconel Welded Pipe Manufacturers in Mumbai, India
When a project cannot afford a pipeline failure, such as subsea gas gathering lines, flue-gas desulphurization units, or aerospace exhaust systems, engineers specify Inconel 625 pipe. Jade Alloys is a Mumbai-based Inconel 625 pipe manufacturer, supplier, and exporter that produces and stocks this alloy to exact ASTM B444 and UNS N06625 requirements, without compromise.
Inconel 625 (UNS N06625, Werkstoff Nr. 2.4856, DIN 2.4856) is a nickel-chromium-molybdenum-niobium alloy prized for its combination of very high strength and outstanding resistance to a wide range of corrosive environments, a chemistry we break down in detail in our guide to Inconel composition and properties. It doesn’t rely on a protective oxide layer alone; its solid-solution strengthening from molybdenum and niobium keeps it stable from cryogenic temperatures up to roughly 980°C, which is why alloy 625 pipe and alloy 625 tube remain the specification of choice across offshore, aerospace, and chemical processing industries where failure is not an option.
As an ISO-certified Inconel 625 pipe manufacturer based in Mumbai, India, Jade Alloys stocks Inconel 625 pipe and Inconel 625 tube in seamless, welded, and ERW construction, in round, square, and rectangular profiles, ready for immediate dispatch or custom production runs. Our production and testing facilities are built around ASTM B444, ASTM B705, and ASME SB444 specifications, giving EPC contractors, OEMs, and procurement teams a single, traceable source for every dimension of alloy 625 piping their project calls for.
Whether your requirement is a single length of Inconel 625 seamless pipe for a repair job or a full container load of alloy 625 ERW pipe for a new offshore installation, Jade Alloys combines mill-grade quality control with the responsiveness of a stockist. Every consignment ships with complete mill test certification, and our sales engineers can advise on the correct schedule, wall thickness, and end finish for your application, not just quote a size off a catalogue. Buyers researching Inconel 625 pipe price, alloy 625 tube specifications, or ASTM B444 N06625 dimensional standards will find the complete technical reference (chemical composition, mechanical properties, equivalent grades, schedule charts, weight charts, and pressure ratings) in the sections below.

Inconel 625 Chemical Composition (ASTM B444 / UNS N06625)
| Element | Ni | Cr | Mo | Nb+Ta | Fe | C | Mn | Si | Al | Ti | S |
|---|---|---|---|---|---|---|---|---|---|---|---|

Niobium is the detail competitors’ pages routinely leave out: it’s the element that stabilizes the alloy against sensitization during welding, which is exactly why Inconel 625 pipe is chosen for welded pressure vessels where stainless steel would need post-weld heat treatment. For a deeper look at how these elements shape alloy behavior across the Inconel family, see our guide to understanding Inconel material properties, composition, and grades.

Applications of Inconel 625 Pipes & Tubes
Every batch of Inconel 625 pipe and tube produced or sourced by Jade Alloys follows a documented process chain:
- Raw Material Sourcing: nickel-alloy billets and coils sourced from approved international mills with full chemical traceability.
- Hot/Cold Working: seamless pipe is hot-extruded or pilgered; tube is cold-drawn to final dimensional tolerance.
- Solution Annealing: heat treatment restores ductility and dissolves precipitates formed during working.
- Pickling & Surface Finishing: acid pickling removes scale; bright-annealed or polished finishes are available on request.
- Testing & Inspection: dimensional, chemical, and mechanical verification
- Marking & Packing: heat-number stamping, color coding, and export-grade packaging.
Our full quality policy and certifications cover every stage of this process.
