Complete Range of Nickel Alloy Products

Shanghai Hangbo Alloy Group supplies the complete range of nickel-alloy product forms — round bars and rods, seamless tubes and pipes, plates and sheets, precision strips, forgings, and welding wire — in more than 200 grades covering Inconel, Hastelloy, Monel, Incoloy, Nimonic, pure nickel and cobalt superalloys.

All material is melted from a fully virgin, prime charge using vacuum induction melting (VIM) and, where the specification calls for it, electroslag remelting (ESR) or vacuum arc remelting (VAR). Every batch is finished to ASTM, ASME, DIN and AMS standards and shipped with EN 10204 3.1 certificates, with third-party inspection available on request. Whether you need a single machined bar or a container-load of seamless heat-exchanger tube, we match the form, grade and temper to the service.

How to Choose the Right Form and Grade

Choosing a nickel alloy starts with two independent decisions: the product form (how the metal is shaped) and the grade (what the metal is made of). The form is set by your manufacturing route — machining, bending, rolling, welding or forging — while the grade is set by the service environment: temperature, corrosive media, pressure and mechanical load.

• Round bars & rods — ideal for machined components such as shafts, valves, pump parts and fasteners. Specify diameter, length, the ASTM grade (for example ASTM B446 for Inconel 625 bar) and the heat-treatment condition.
• Seamless tubes & pipes — for high-pressure, high-temperature fluid service in chemical, petrochemical and power plants. Choose seamless over welded where the code requires it or where the wall must carry pressure without a longitudinal seam. Common standards are ASTM B163, B444, B622 and B167.
• Plates & sheets — for vessels, lining, heat-exchanger tube sheets and fabricated tanks. Specify hot-rolled or cold-rolled, thickness, width, and whether you need the as-rolled or solution-annealed condition.
• Precision strips — thin, cold-rolled strip with tight tolerances for springs, electronic contacts, battery connectors and heat-exchanger fins.
• Forgings — flanges, rings, discs and bespoke shapes where grain flow and mechanical integrity matter. Forging refines the grain structure for superior strength and fatigue life.
• Welding wire — matching filler metal for every base grade, supplied as TIG wire, MIG spools or SAW coils, so the weld chemistry matches the parent metal.

Matching Grade to Service

Once the form is fixed, select the grade by the environment. Inconel 625 and Hastelloy C-276 handle aggressive chlorides, pitting and crevice corrosion; Monel 400 and K-500 suit seawater and hydrofluoric acid; Incoloy 800 / 800H / 800HT cover high-temperature oxidation; pure Nickel 200/201 serve caustic duty; and Inconel 718 or 617 provide high-temperature strength. If you are unsure, our engineers will recommend the grade that meets your specification at the lowest cost.

Standards and Certification

Every product ships with EN 10204 3.1 certification and full traceability to the melt. We supply to ASTM, ASME, AMS, DIN and EN specifications, and can arrange EN 10204 3.2 witnessed testing or third-party inspection for critical applications. Contact our sales team for a quotation and technical support within 24 hours.
