Hastelloy C276 Plates, Sheets, Circles, Bars & Pipes – UNS N10276

Hastelloy C276 (UNS N10276) – Stockist, Supplier and Processor in Mumbai Since 1992

Hastelloy C276 (UNS N10276, W.Nr 2.4819) is a nickel-molybdenum-chromium alloy with tungsten, and one of the most versatile corrosion-resistant alloys available. It withstands wet chlorine gas, hypochlorite, chlorine dioxide, ferric and cupric chlorides, hot contaminated mineral acids and seawater, and its very low carbon content limits grain-boundary precipitation during welding. Ganesh Metals, a stockist, supplier and processor in Mumbai since 1992, supplies C276 plate, sheet and strip to ASTM B575 / ASME SB575, bar to ASTM B574, seamless pipe to ASTM B622, welded pipe to B619, welded tube to B626 and fittings to ASTM B366, all with EN 10204 3.1 MTCs and heat-number traceability.

We supply Hastelloy C276 sheet and plate cut to size. Thin sheet goes into reactor linings, scrubber ducts and heat-exchanger plates, while thicker plate is cut into tube sheets, nozzles, flanges and circles. We cut to your size in Mumbai, mark the heat number on every piece and send it with the EN 10204 3.1 MTC. Share thickness, width, length and quantity for a quote.

C276 is the default choice when a process mixes oxidising and reducing chemistry, or when chlorides and acids are both present. It is more expensive than Incoloy 825 or 316L, so we often help buyers confirm whether C276 is truly needed or whether C22 or 825 will do. Share your media, temperature and concentration and we will discuss the options.

Why Choose Hastelloy C276?

Hastelloy C276 offers outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking, handles both oxidising and reducing media, and can usually be used in the as-welded condition. Its high molybdenum content is the key to its performance in reducing acids.

Applications:

Hastelloy C276 is specified for the harshest mixed-acid and chloride environments in process plants.

  • Chemical Processing: Reactors, columns and piping for hot hydrochloric, sulphuric and mixed acids.

  • Pharma Equipment: Reactors, dryers and transfer lines handling aggressive reagents and chlorinated solvents.

  • Pollution Control: Flue-gas desulphurisation scrubbers, ducts and dampers in power and process plants.

  • Heat Exchangers: Tubes and plates for acid-bearing and chloride-contaminated process exchangers.

  • Oil & Gas: Sour-gas equipment and components exposed to H₂S, chlorides and elemental sulphur.

Hastelloy C276 is supplied as plates and sheets, strip and coils, discs and circles, round bars, seamless and welded pipes and tubes, flanges and fittings. Sizes on request – share dimensions and quantity.

Hastelloy C276: Specs, Sizes & Equivalents

C276 plate is frequently cut into tube sheets, nozzles and circles for vessel fabricators. Every cut piece is marked with the original heat number, PMI confirms the grade, and the cutting record links each piece to the MTC – important because C276 and C22 look identical on the shop floor.

FAQ: What is the difference between C276 and C22?

  • C22 has more Cr; C276 has more Mo and W.

  • Q: Which spec covers Hastelloy C276 plate? A: ASTM B575 / ASME SB575, supplied with an EN 10204 3.1 MTC.

  • Q: Can C276 be used as welded? A: Generally yes; its low carbon limits sensitisation, though procedures should follow your code.

Hastelloy C276 Equivalent Grades & FAQ

  • Equivalent grades: UNS N10276 · W.Nr 2.4819 · DIN NiMo16Cr15W · ISO NW0276 · also written C-276 or Alloy C276.

  • Q: Do you supply C276 circles and cut pieces? A: Yes, cut to size from certified plate with heat numbers marked.

  • Q: What affects Hastelloy C276 price in India? A: Hastelloy C276 pricing moves with nickel, molybdenum and tungsten market levels, the form you need (plate, sheet, circle, bar or pipe), thickness or diameter, quantity and whether the material is cut to size. An EN 10204 3.1 MTC with heat-number

  • Q: Is Hastelloy C276 magnetic? A: No. Annealed C276 is non-magnetic, so a magnet test can't confirm the grade. We confirm it with PMI and the heat number on the EN 10204 3.1 MTC.

  • Q: How do I work out the weight of a C276 plate? A: Use density 8.89 g/cm³. Our free metal weight calculator does the maths for sheet, plate, bar and pipe.

  • Q: Do you deliver C276 outside Mumbai? A: Yes. We supply across India, including SEZ units, from Mumbai. That includes Dahej, Vadodara, Ahmedabad, Pune, Bangalore and Chennai.
