Hastelloy C22 Plates, Sheets, Bars & Pipes – UNS N06022

Hastelloy C22 (UNS N06022) – Stockist, Supplier and Processor in Mumbai Since 1992

Hastelloy C22 (UNS N06022, W.Nr 2.4602) is a nickel-chromium-molybdenum-tungsten alloy with higher chromium than C276, giving it better resistance to oxidising media such as nitric acid, ferric and cupric ions and wet chlorine, while keeping excellent resistance to reducing acids, pitting and crevice corrosion. As a stockist, supplier and processor in Mumbai since 1992, Ganesh Metals supplies Hastelloy C22 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. Every order carries an EN 10204 3.1 mill test certificate and heat-number traceability.

We supply Hastelloy C22 sheet and plate cut to size. Thin sheet goes into reactor and dryer linings and scrubber ducts, 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.

Hastelloy C22 is often chosen for multi-purpose plants where the same equipment sees different chemistries over its life, such as pharmaceutical and fine-chemical reactors. It is also used as an upgrade where C276 suffers in oxidising conditions. If you are unsure which C-type alloy fits, send your process details and we will help compare C22, C276 and C-4.

Why Choose Hastelloy C22?

Hastelloy C22 resists both oxidising and reducing chemicals, localised attack and chloride stress-corrosion cracking, and is highly resistant to weld-zone corrosion. Its balanced chemistry makes it one of the most universal choices among nickel alloys.

Applications:

Hastelloy C22 is selected for multi-purpose and oxidising process duties where C276 may fall short.

  • Pharma Equipment: Multi-product reactors, dryers and filters handling changing reagents and solvents.

  • Chemical Processing: Equipment for nitric, mixed and chlorinated acid streams with oxidising ions.

  • Pollution Control: Scrubber parts, outlet ducts and mist eliminators in flue-gas cleaning systems.

  • Heat Exchangers: Plates and tubes exposed to oxidising, chloride-contaminated process fluids.

  • Oil & Gas: Components for sour service where both pitting and oxidising conditions are present.

For multi-purpose plants, C22 comes as plate for shells, sheet for liners, bar for shafts and agitators, and B622 pipe or B626 tube for process lines. Discs, circles and fittings are also available; sizes on request.

Hastelloy C22: Specs, Sizes & Equivalents

Because C22 and C276 are identical in appearance, we PMI-check C22 before dispatch and keep the original mill markings and heat numbers on every plate, bar and tube. Quoted availability is valid for 2 days, after which stock is reconfirmed before the order is booked.

FAQ: Is Hastelloy C22 better than Hastelloy C276?

  • Better in oxidising media; similar in reducing.

  • Q: Which spec covers Hastelloy C22 bar? A: ASTM B574 / ASME SB574, supplied with an EN 10204 3.1 mill test certificate.

  • Q: Do you supply C22 seamless pipe? A: Yes, to ASTM B622, with welded pipe to B619 and welded tube to B626 also available.

Hastelloy C22 Equivalent Grades & FAQ

  • Equivalent grades: UNS N06022 · W.Nr 2.4602 · DIN NiCr21Mo14W · ISO NW6022 · also written C-22 or Alloy 22.

  • Q: Is C22 suitable for pharma reactors? A: Yes, it is widely used in multi-purpose pharmaceutical equipment.

  • Q: What affects Hastelloy C22 price in India? A: Hastelloy C22 pricing moves with nickel, chromium and molybdenum market levels, the form you need (plate, sheet, bar or pipe), thickness or diameter, quantity and whether the material is cut to size. An EN 10204 3.1 MTC with heat-number traceability is included. Send your size and quantity for a current quote.

  • Q: Is Hastelloy C22 magnetic? A: No. Annealed C22 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 C22 plate? A: Use density 8.69 g/cm³. Our free metal weight calculator does the maths for sheet, plate, bar and pipe.

  • Q: Do you deliver C22 outside Mumbai? A: Yes. We supply across India, including SEZ units, from Mumbai. That includes Dahej, Vadodara, Ahmedabad, Pune, Bangalore and Chennai.
