Hastelloy C22 Plate in Chennai for Oxidising Acids and Pharma Reactors

Hastelloy C22 Plate in Chennai for Oxidising Acids and Pharma Reactors

Hastelloy C22 plate and sheet for oxidising and mixed-acid duty, and for pharma process equipment built around Alathur, Sriperumbudur and Ambattur. C22 carries more chromium than C276, so it is the usual choice when the stream is strongly oxidising — ferric or cupric salts, free chlorine at higher levels, or mixed acids that swing between reducing and oxidising. Ganesh Metals cuts C22 plate to size and has been a high-nickel alloy stockist, supplier and processor in Mumbai since 1992.

We provide direct door delivery to your company in Chennai. C22 plate is cut and packed at our Mumbai shop and supplied from our Mumbai stock to Alathur, Sriperumbudur, Ambattur, Guindy or Manali. Give us the acids, any oxidising species and the temperature, and we will confirm whether C22 or C276 is the better call before we quote.

Hastelloy C22 plate specifications

Hastelloy C22 (UNS N06022, W.Nr 2.4602, NiCr21Mo13W): plate, sheet and strip ASTM B575 / ASME SB575, in the solution-annealed condition.

Companion forms: ASTM B574 bar, ASTM B622 seamless pipe, ASTM B619 welded pipe and ASTM B626 welded tube, with ASTM B366 fittings (WPHC22) and ASTM B564 flanges and forgings.

Pipe, tube and flanges: sizes confirmed per enquiry, from Mumbai stock.

Why the higher chromium matters: C22 was balanced for oxidising and mixed-acid streams that would attack lower-chromium C-family grades. For reducing and mixed-acid work in the Manali belt, see Hastelloy C276 plate in Chennai. Our C276 vs C22 guide sets the two side by side.

Typical chemistry: Cr 20.0–22.5%, Mo 12.5–14.5%, W 2.5–3.5%, Fe 2.0–6.0%, C 0.015% max, Si 0.08% max, nickel balance. Density about 8.69 g/cm³.

Minimum properties, ASTM B575 solution-annealed plate: tensile 690 MPa, yield 310 MPa, elongation 45%.

Equivalents: W.Nr 2.4602 (NiCr21Mo13W). The UNS number on the MTC is what your inspector should check.

C22 plate and sheet: how it is supplied

Pharma and chemical buyers rarely need a whole mill plate of C22. We cut sheet and plate to reactor covers, liner panels, nozzle pads and baffle sizes, punch circles for blanks, and slit strip for weld overlay. The heat number of the parent plate is marked on each cut piece. Use the metal weight calculator to estimate plate weight before you enquire.

Where C22 plate is used around Chennai

Pharma and bulk-drug process equipment around Alathur and Sriperumbudur: C22 plate for reactors, condenser covers and internals in oxidising and mixed-acid service.

Fine-chemical fabricators in Ambattur: C22 sheet for small vessels, dip-pipe flanges and manway covers that see chlorine or mixed acids.

Chemical units whose process swings from reducing to oxidising: C22 where one alloy has to cover the full cycle.

Effluent and gas-cleaning systems that carry free chlorine or strong oxidisers: C22 sheet for ducts, spray zones and vessel linings.

Exchanger shops in Guindy building for these plants: C22 tube sheets and channel covers on the process side.

Why Chennai pharma and chemical buyers order C22 plate from Ganesh Metals

High-nickel alloy stockist, supplier and processor in Mumbai since 1992.

The mill's original EN 10204 3.1 test certificate is passed on with every supply, with heat-number traceability.

ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certified.

C22, C276 and C4 are hard to tell apart once cut, so each lot is PMI-checked against the order grade.

Reactor and liner sizes are cut from stock plate, so a single repair does not mean buying a full sheet.

We will point you to C276 or C4 when the duty is reducing or hydrochloric, rather than selling C22 by default.

FAQs — Chennai

Do you supply Hastelloy C22 plate to Chennai pharma plants?

Yes. We send C22 plate, sheet and strip to Alathur, Sriperumbudur, Ambattur, Guindy and Manali, supplied from our Mumbai stock. We provide direct door delivery to your company in Chennai.

How long does delivery to Chennai take?

That depends on the transporter and route. We confirm the dispatch plan with you when the order is placed.

C22 or C276 plate for an oxidising acid reactor?

C22 is the usual pick when the stream is strongly oxidising or swings between oxidising and reducing. C276 is preferred for reducing and mixed-acid duty with chlorides, as on many Manali jobs. Read the C276 vs C22 guide and send your process data; we will help you choose.

Can you cut C22 plate for a reactor cover or tube sheet?

Yes. Send the drawing or cutting list and the thickness. We cut covers, liners, pads and circles from stock plate and mark the heat number on each piece.

Will C22 plate come with a 3.1 certificate for plant inspection?

Yes. Every supply comes with the mill's original EN 10204 3.1 test certificate, and heat numbers are marked on each piece. Call +91 22 6636 2372 or WhatsApp +91 99872 73700 to discuss your use.
