Inconel 625 Plate in Chennai for Heat-Exchanger Tube Sheets and Shells

Inconel 625 Plate in Chennai for Heat-Exchanger Tube Sheets and Shells

Inconel 625 plate and sheet for Chennai exchanger and vessel shops, cut to tube-sheet, shell and nozzle-pad sizes. Fabricators in Ambattur Industrial Estate, Thirumudivakkam and the Sriperumbudur belt use 625 where seawater, chlorides or hot acid condensate would crack or pit lesser alloys, and where the drawing needs a weldable, high-strength nickel-chromium-molybdenum plate. Ganesh Metals has been a high-nickel alloy stockist, supplier and processor in Mumbai since 1992, and every plate leaves with its EN 10204 3.1 mill certificate.

We provide direct door delivery to your company in Chennai. Plate is cut and packed at our Mumbai shop and supplied from our Mumbai stock to Ambattur, Thirumudivakkam, Guindy, Sriperumbudur or Irungattukottai once we agree the dispatch plan. Send the tube-sheet drawing or a cutting list and we will check thickness and grade before quoting.

Inconel 625 plate grades and specifications

Inconel 625 (UNS N06625, W.Nr 2.4856, NiCr22Mo9Nb): plate, sheet and strip ASTM B443 / ASME SB443. Grade 1 (annealed) is the usual choice for exchangers and vessels up to about 593 °C; Grade 2 (solution annealed) is specified for higher-temperature creep service.

Matching forms for the same job: round bar ASTM B446, seamless pipe and tube ASTM B444, welded pipe ASTM B705, welded tube ASTM B704, fittings ASTM B366 (WPNCMC), forgings and flanges ASTM B564.

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

Welding note: 625 plate is normally joined with ERNiCrMo-3 filler. Tube-to-tubesheet welds and overlay on carbon-steel tube sheets use the same family of consumables, so one filler covers most exchanger jobs.

Typical chemistry: Ni 58% min, Cr 20–23%, Mo 8–10%, Nb+Ta 3.15–4.15%, Fe 5% max, C 0.10% max. Density about 8.44 g/cm³.

Minimum properties, ASTM B443 Grade 1 annealed plate: tensile 827 MPa, yield 414 MPa, elongation 30%. Grade 2 solution-annealed plate: tensile 690 MPa, yield 276 MPa, elongation 30%.

Thickness range: thin sheet for overlay and liners through to heavy plate for tube sheets. Tell us the finished thickness and machining allowance on the drawing, and we will quote the nearest stock plate.

625 plate and sheet: what we cut

Our main line is sheet, plate and coil, so most Chennai orders for 625 are flat material cut to a list: rectangles for shells and nozzle pads, strips for weld overlay, and circles punched in-house from about 30 mm to 300 mm for baffles and small blanks. Larger circles and full tube sheets are cut to your drawing. Each cut piece carries the heat number from the parent plate. Work out plate weights with the metal weight calculator before you enquire.

1. Call +91 22 6636 2372, WhatsApp +91 99872 73700 or email sales@ganeshmetals.com with the grade (625 Grade 1 or Grade 2), form, plate thickness, cut sizes or drawing, quantity and the code your inspector will check against. You can also use our enquiry form.

2. We confirm stock and send price, availability and the MTC heat number.

3. You confirm the order and the transporter. We cut, mark, pack, dispatch and share the documents.

Where 625 plate goes in Chennai fabrication

Tube-sheet and channel fabricators in Ambattur Industrial Estate: thick 625 plate for tube sheets, or thinner plate for overlay where the base is carbon steel.

Exchanger shell and bundle shops in Thirumudivakkam and Guindy: 625 sheet rolled into shells, with circles for baffles and support plates.

Process-skid and vessel builders in the Sriperumbudur and Irungattukottai belt: nozzle reinforcement pads, flanged covers and wear plates in 625.

Seawater cooler and condenser work for coastal plants around Ennore: 625 plate where chloride pitting and crevice attack rule out lower grades.

Flue-gas and scrubber fabrication: 625 sheet for liners and ducts carrying hot acid condensate.

Why Chennai fabricators order 625 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.

Plate is cut to your nesting list, so a tube sheet arrives near size and the offcut stays here, not in your scrap bin.

PMI on 625 plate before dispatch, because 625, 600 and 601 offcuts look the same on a shop floor.

Grade 1 or Grade 2 condition is read off the MTC against your order before cutting starts.

FAQs — Chennai

Do you supply Inconel 625 plate to Chennai?

Yes. We send 625 plate, sheet and cut circles to Ambattur, Thirumudivakkam, Guindy, Sriperumbudur and Irungattukottai, 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.

Can you cut a full 625 tube sheet to our drawing?

Yes. Small circles are punched in-house from about 30 mm to 300 mm. Larger circles and tube sheets are cut to drawing from stock plate, with the heat number transferred to each piece. Send the drawing and the plate thickness you need.

Should we buy 625 Grade 1 or Grade 2 plate for an exchanger?

Most exchanger and vessel drawings call for Grade 1 (annealed). Grade 2 is chosen when the design runs hot enough for creep strength to matter. Check your design code or tell us the operating temperature and we will help confirm.

Will the 625 plate come with a 3.1 certificate for the inspector?

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.
