Hastelloy C276 Pipe

Steel Pipe & Tubes has been a leading supplier of Hastelloy piping solutions.

Hastelloy C-276 (UNS N10276, W.Nr. 2.4819) is a powerful nickel chromium molybdenum alloy that has been made an outstanding choice in the production of seamless and welded pipes that can work under very corrosive conditions. C276 is a nickel-based, engineered, pitting-resistant, crevice-corrosion, and stress-corrosion-cracking (SCC) alloy that is used in pipes conducting chlorides, mixed acids, sour gases, and high-temperature brines where the stainless steels or duplex grades or standard nickel alloys fail. Hastelloy C276 pipes conform to specifications ASTM B622 and ASTM B619 fully and have been demonstrated to be used in situations where high functionality is required in chemical processing, offshore operations, pollution control operations, and high-purity applications.

Hastelloy C276 Pipe Manufacturer & Supplier in India

Stellar Alloys Steel Pipes and Tubes is one of the leading hastelloy C276 tube suppliers, manufacturers and stockists, which were developed to be used in highly corrosive process environments. Our C276 Alloy pipes and tubes are manufactured in full compliance with ASTM B622 in the construction of seamless and ASTM B619 in the construction of welded pipes, giving a successful application in chemical processing units, flue-gas desulfurization plants, offshore systems, petrochemical circuits, and high-temperature utility lines. We are also supporting C276 projects with some other corrosion-resistant grades like our Hastelloy C22 Pipe, which has found favor in some mixed-acid, oxidizing environments. UNS N10276 grade that has composition W.Nr. 2.4819 is highly resistant to pitting, crevice corrosion, and stress-corrosion cracking and is therefore the material of choice in situations where stainless steel, duplex, or even normal nickel alloys are not able to sustain structural integrity over time.

The C276 pipes are each solution-annealed and then subjected to closely controlled melting and forming conditions to achieve consistent and reliable corrosion resistance and microstructure. Our product range is extensive in terms of round, square, and rectangular SCH 10, SCH 40, and SCH 80, including the ability to provide cut-to-length inventory to meet project-specific needs and U-bend tubes and prefabricated spools. The dimensional accuracy is ensured by strict controls of OD and WT, and all heat can be traced by complete documentation.

All supplies are made with quality dossiers that contain EN 10204 3.1 MTCs, PMI test reports, and inspection plans prepared in accordance with ASTM, ASME, and international codes on pressure piping. Engineering teams that are operating according to ASME B31.3 and B31.1 guidelines can receive dimensional inspection reports, NDT summaries, and code-ready documentation to guarantee smooth approval and commissioning. Such a blend of technical dependability, formal quality control, and the availability of ready inventories makes Stellar Alloys Steel Pipes and Tubes a reliable provider of the Hastelloy C276 pipes and tubes for critical uses globally.

Frequently Asked Questions About Hastelloy C276 Pipes and Tubes

The Hastelloy C276 pipe is produced per ASTM B622 to be produced seamlessly and ASTM B619 or B626 to be welded. These specification outline the practice of melting, chemical, mechanical, limits, heat treatment, and dimensional allowances that provide uniform performance at high temperature corrosive conditions.

Hastelloy C276 is applied in chemical work, desulfurization of flue-gasses, mixed acid, sour-gas systems and high-salinity brines and pollution control devices. Being pitting, crevice corrosion and stress-corrosion cracking resistant, it can be used in the demanding chloride- and acid-containing applications.

C276 pipe is made of a nickel-chromium-molybdenum alloy with additions of tungsten and very low carbon and silicon content. This composition offers stability in oxidizing and reducing environments, minimizing grain-boundary precipitation and preserving corrosion resistance in the as-welded condition.

Hastelloy C276 pipes are typically available from small-bore instrumentation sizes to large process diameters, covering schedules SCH 5S through SCH 160. Custom OD, wall thickness, U-bend tubes and fabricated spools can also be supplied based on project requirements.

Yes. Hastelloy C276 is very resistant against pitting and crevice corrosion in chloride-bearing sea water, high temperature brines and high salinity process streams. It is stable both in oxidizing and reducing chloride systems thus it has been used as one of the most reliable materials in marine and offshore applications.

Hastelloy C276 pipes are typically subjected to PMI, hydrostatic testing, eddy-current testing, ultrasonic examination, visual and dimensional checks and mechanical testing as per ASTM and ASME requirements. These tests ensure material integrity, traceability and compliance for critical services.

Yes. The supplies are EN 10204 3.1 MTCs, PMI reports, dimensional inspection results, NDT summaries and test certificates consistent with ASTM B622, B619 and B626. MDRs are also available upon request in MDRs of ASME B31.3 and B31.1.
