Hastelloy C276 for Manali Petrochemical and Fertiliser Plants, from Mumbai Stock

Hastelloy C276 for Manali Petrochemical and Fertiliser Plants, from Mumbai Stock

Maintenance crews in the Manali petrochemical and fertiliser belt often need Hastelloy C276 during a shutdown or a vessel repair: a patch plate, a nozzle pad, a liner panel or a short length of process pipe. C276 is the nickel-molybdenum-chromium alloy with tungsten that copes with mixed acids, wet chlorine and chloride-bearing streams in the same unit. Ganesh Metals has been a stockist and supplier of high-nickel alloys in Mumbai since 1992. C276 is supplied from Mumbai stock, with sizes confirmed per enquiry, and every lot carries an EN 10204 3.1 mill test certificate.

We provide direct door delivery to your company in Chennai. Material is cut and packed at our Mumbai shop and sent into Manali, Tiruvottiyur, Ponneri and the neighbouring North Chennai industrial stretch. There is no Ganesh Metals branch in Chennai. Send the form, the size or drawing, the process medium and the temperature, and we will confirm what can be supplied before we quote.

C276 in the Manali petrochemical and fertiliser belt

Manali is North Chennai's main petrochemical and fertiliser cluster, with chemical units also working in nearby Tiruvottiyur and towards Ponneri. The duty that usually brings a buyer to C276 is mixed-acid or chloride-bearing service: scrubbers, absorbers, process vessels, transfer lines and repair patches where a single-purpose alloy would not last.

Fertiliser and acid plants in this belt also see sulphuric and phosphoric streams, sometimes with chlorides. Incoloy 825 is often enough for straightforward sulphuric or phosphoric duty; C276 is the usual step up when the stream is hotter, mixed, or carries chlorides or wet chlorine. Share the acids and temperature and we will say which grade fits, rather than defaulting to C276.

This page is the area guide for buying C276 into Manali. For cut plate, liners and tube sheets see Hastelloy C276 plate in Chennai. For process lines, see C276 pipe and tube in Chennai. Grade data sits on Hastelloy C276.

C276 chemistry table (ASTM B575, wt%): Mo 15.0–17.0; Cr 14.5–16.5; W 3.0–4.5; Fe 4.0–7.0; Co 2.5 max; Mn 1.0 max; V 0.35 max; C 0.010 max; Si 0.08 max; P 0.04 max; S 0.03 max; nickel balance. Density about 8.89 g/cm³. These figures match the ranges on our C276 grade page.

Minimum mechanicals, ASTM B575 solution-annealed plate: tensile 690 MPa, yield 283 MPa, elongation 40%. The same chemistry underpins pipe and tube to ASTM B622 (seamless) and B619 / B626 (welded).

How C276 and C22 part company in this belt: C276 is the general choice for reducing and mixed-acid work with chlorides; C22 is preferred when the stream is strongly oxidising. The C276 vs C22 acid-service guide sets out the difference.

Identity on the certificate: UNS N10276, W.Nr 2.4819, EN NiMo16Cr15W. C276 and C22 look the same once cut, so the UNS number on the EN 10204 3.1 mill test certificate, and a grade check against it, are what your inspector should use.

Plate cutting and welding for Manali repairs

Most Manali orders are not a full mill plate. We cut C276 sheet and plate into patch plates, liner panels, nozzle pads and baffle sizes, and we can slit strip for weld overlay. Pipe and tube are cut to a length list. Every cut piece keeps the parent heat number. When a patch is welded in place, the low carbon (0.010% max) and low silicon in C276 help limit sensitisation in the heat-affected zone; your welding procedure still governs the job. Pipe, tube and flanges: sizes confirmed per enquiry, from Mumbai stock.

How to enquire for C276 from a Manali plant

1. Email sales@ganeshmetals.com, call +91 22 6636 2372 or WhatsApp +91 99872 73700 with the grade (C276 / UNS N10276), the form (plate, sheet, strip, pipe or tube), thickness or wall, cut sizes or a drawing, quantity, and the acids and temperature.

You can also use the enquiry form.

2. We check Mumbai stock, confirm the size, and send the price with the mill-certificate heat number.

3. Once you accept the offer and name the transporter, we cut, mark, pack and dispatch, and we pass on the documents with the consignment.

Why Manali plants buy C276 from Ganesh Metals

Ganesh Metals has been a high-nickel alloy stockist, supplier and processor in Mumbai since 1992.

Each supply is accompanied by the mill's original EN 10204 3.1 test certificate, and the heat number is marked on every cut piece.

The Mumbai shop is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018.

We will tell you if Incoloy 825 or Hastelloy C22 is a better fit for the stream, instead of selling C276 by default.

Plate can be cut to a repair list, so a single patch does not force you to take a full sheet.

Door delivery into the Manali belt

We provide direct door delivery to your company in Chennai. C276 is supplied from Mumbai stock to addresses in Manali and the adjoining industrial areas.

Tell us the plant gate or workshop address and your preferred transporter when you confirm the order. Transit time is not a fixed number; it depends on the route and the carrier we agree with you.

SEZ and bonded units in the wider Chennai area can be supplied on the same basis, still from Mumbai stock, with the documents your stores team needs.

For weight estimates before you enquire, use the metal weight calculator.

If the job needs both plate and pipe in the same grade, send both lists together so the heat and documents can be planned as one supply.

Full Hastelloy coverage for Chennai, including other C-family grades, is summarised on Hastelloy in Chennai.

Do you keep a warehouse in Manali, or does C276 come from Mumbai?

C276 for Manali is supplied from Mumbai stock. We do not have a warehouse or office in Manali or elsewhere in Chennai. We provide direct door delivery to your company in Chennai.

Can one order cover both C276 plate and pipe for a Manali shutdown?

Yes. Send the plate cutting list and the pipe or tube sizes (outside diameter, wall or schedule, seamless or welded, length) in the same enquiry. Sizes are confirmed per enquiry against Mumbai stock, and each piece is marked with its heat number for the shutdown file.

Is C276 or Incoloy 825 the better choice for a Manali fertiliser or acid unit?

825 often covers straightforward sulphuric or phosphoric service. C276 is the usual upgrade when chlorides, wet chlorine or mixed acids are present, or when the temperature is higher. Send the medium and temperature and we will help you compare; see also Incoloy 825 and the C276 vs C22 guide.

How is C276 plate prepared for a welded vessel patch?

We cut the patch or nozzle pad to your size or drawing and mark the parent-plate heat number on the piece. C276's low carbon helps welded repairs, but the welding procedure is yours to follow. If you need strip for overlay, tell us the width and thickness.

Will a Manali plant inspector receive an EN 10204 3.1 certificate with C276?

Yes. The mill's original EN 10204 3.1 test certificate travels with the supply, and heat numbers on the pieces can be checked against it. Email sales@ganeshmetals.com or call +91 22 6636 2372 if your stores team needs the documents listed out before dispatch.
