Hastelloy C276 Plate in Chennai for Manali Petrochemical and Acid Service

Hastelloy C276 Plate in Chennai for Manali Petrochemical and Acid Service

Hastelloy C276 plate and sheet for the Manali petrochemical belt and the chemical units around it. Maintenance and fabrication teams in Manali, Tiruvottiyur and Gummidipoondi choose C276 when a vessel, scrubber or line sees mixed acids, wet chlorine, hypochlorite or chloride-laden process streams together, the kind of mix that defeats single-purpose alloys. Ganesh Metals cuts C276 plate to your sizes 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. C276 plate is cut and packed at our Mumbai shop and supplied from our Mumbai stock to Manali, Tiruvottiyur, Ennore, Gummidipoondi or Ambattur. Give us the acids, their strength and the temperature, and we will confirm whether C276 is the right call before we quote.

Hastelloy C276 plate specifications

Hastelloy C276 (UNS N10276, W.Nr 2.4819, NiMo16Cr15W): plate, sheet and strip ASTM B575 / ASME SB575, in the solution-annealed condition.

Matching material for the same equipment: bar ASTM B574, seamless pipe ASTM B622, welded pipe ASTM B619, welded tube ASTM B626, fittings ASTM B366 (WPHC276), forgings and flanges ASTM B564.

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

Why the low carbon matters: C276 is made with very low carbon and silicon, so the heat-affected zone next to a weld does not sensitise. Most Manali repairs are welded in place, so this is the property that keeps a patch from failing beside the weld.

Typical chemistry: Mo 15–17%, Cr 14.5–16.5%, W 3–4.5%, Fe 4–7%, C 0.010% max, Si 0.08% max, nickel balance. Density about 8.89 g/cm³.

Minimum properties, ASTM B575 solution-annealed plate: tensile 690 MPa, yield 283 MPa, elongation 40%.

Equivalents: W.Nr 2.4819 (NiMo16Cr15W). C276 is also widely sold as Alloy C-276; the UNS number on the MTC is what your inspector should check.

C276 plate and sheet: how it is supplied

Petrochemical and chemical buyers rarely need a whole mill plate of C276. We cut sheet and plate to liner panels, nozzle pads, baffle sizes and patch plates, punch circles for blanks and dished-end discs, and supply strip for weld overlay. Every cut piece carries the heat number of its parent plate. Check weights with the metal weight calculator.

Why Manali buyers order C276 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.

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

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

We tell you plainly when C22 or 825 suits your duty better, rather than selling C276 by default.

Yes. We send C276 plate, sheet and strip to Manali, Tiruvottiyur, Ennore, Gummidipoondi and Ambattur, 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.

C276 or C22 plate for a Manali scrubber?

C276 is the usual pick for reducing and mixed-acid duty with chlorides. C22 holds up better when the stream is strongly oxidising, such as with ferric or cupric salts or free chlorine at higher levels. Our C276 vs C22 guide explains the choice; send your process data and we will help.
