Inconel 625 for Heat-Exchanger and Vessel Shops in Ambattur Industrial Estate

Inconel 625 for Heat-Exchanger and Vessel Shops in Ambattur Industrial Estate

Ambattur Industrial Estate is one of Chennai's largest clusters of heat-exchanger, pressure-vessel and general engineering shops. Those shops usually need Inconel 625 in more than one form at a time: plate for tube sheets, shells and nozzle pads; discs and circles for baffles and blanks; and bar for turned parts. Alloy 625 is a niobium-strengthened nickel-chromium-molybdenum grade that holds its strength without age-hardening and resists seawater and chloride attack. Ganesh Metals has stocked and processed high-nickel alloys in Mumbai since 1992, and 625 is supplied from Mumbai stock with an EN 10204 3.1 mill test certificate.

We provide direct door delivery to your company in Chennai. Cut plate, discs and bar are packed in Mumbai and sent into Ambattur Industrial Estate and the nearby shops in Guindy, Thirumudivakkam and Vanagaram. We do not operate a Chennai office. Send the form, the size or drawing and the duty, and we will confirm availability before quoting.

625 forms and size range for Ambattur shops

Size-range table (confirm each size per enquiry, from Mumbai stock): plate and sheet, cut to a list or drawing; discs and circles punched in-house from about 30 mm to 300 mm; larger circles and tube sheets cut to drawing; round bar cut to your length list; pipe, tube and flanges available, with sizes confirmed per enquiry.

Inconel 625 (UNS N06625, W.Nr 2.4856): plate, sheet and strip to ASTM B443 / ASME SB443; bar to ASTM B446; seamless pipe and tube to ASTM B444; welded pipe to B705 and welded tube to B704; fittings to B366 (WPNCMC); flanges to B564.

Plate-led jobs are covered in detail on Inconel 625 plate in Chennai. For punched blanks and baffles, use 625 discs and circles in Chennai. Bar, pipe and the Chennai Inconel hub are linked at the end of this page.

Grade 1 (annealed) is the usual condition for exchanger and vessel work up to moderate temperature. Grade 2 (solution annealed) is specified when the design needs higher-temperature creep strength. The condition is read off the mill certificate before we cut.

Inconel 625 mechanicals table (ASTM minimums): B443 / B446 Grade 1 annealed — tensile 827 MPa, yield 414 MPa, elongation 30%. Grade 2 solution annealed — tensile 690 MPa, yield 276 MPa, elongation 30%. Density about 8.44 g/cm³.

Typical chemistry (ASTM B443, wt%): Ni 58.0 min; Cr 20.0–23.0; Mo 8.0–10.0; Nb+Ta 3.15–4.15; Fe 5.0 max; C 0.10 max. These figures match ASTM B443 / UNS N06625.

Mechanicals, condition and inspection

Inspectors in Ambattur shops should check the UNS number N06625 and the B443 or B446 grade (Grade 1 or Grade 2) on the EN 10204 3.1 certificate, and match them to the heat number marked on each cut piece. 625, 600 and 601 offcuts can look alike on a shop floor, so the certificate and marking matter more than appearance.

Shops and duties inside Ambattur Industrial Estate

Heat-exchanger builders in the estate use 625 plate for tube sheets and channel parts, and thinner sheet or punched circles for baffles, when the process side or the cooling medium is seawater or a chloride-bearing stream.

Vessel and skid shops in Ambattur, and in neighbouring Thirumudivakkam and Guindy, roll 625 sheet into shells and use plate for nozzle reinforcement pads and covers.

Contract machine shops in the estate turn 625 bar into sleeves, rings and small shafts for corrosive duty. For a bar-only enquiry, see Inconel 625 round bar in Chennai.

How to order 625 for an Ambattur shop

1. Email sales@ganeshmetals.com, call +91 22 6636 2372 or WhatsApp +91 99872 73700 with the grade (625 / UNS N06625), Grade 1 or Grade 2 if known, the form, thickness or diameter, cut sizes or drawing, and quantity. The enquiry form is also open.

2. We confirm what is available from Mumbai stock and return the price with the heat number that will appear on the mill certificate.

3. You accept the offer and name the carrier. We cut, mark and pack in Mumbai, then dispatch and share the documents.

Some jobs from the Sriperumbudur and Oragadam auto and electronics corridor also come through Ambattur fabricators. If the part is a tube sheet, a disc or a cut plate, send the drawing here and we will confirm the form.

When you confirm the order, tell us the plot or gate inside Ambattur Industrial Estate and the transporter you want to use.

Why Ambattur fabricators order 625 from Ganesh Metals

High-nickel alloy stockist, supplier and processor in Mumbai since 1992, certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018.

The mill's original EN 10204 3.1 test certificate is supplied with the material, and the heat number stays on every cut plate, disc and bar length.

We provide direct door delivery to your company in Chennai, including workshops inside Ambattur Industrial Estate, supplied from Mumbai stock.

One enquiry can cover plate, discs and bar, so a shop does not have to split a single equipment job across several sellers.

If a cheaper form will do — a disc blank instead of a bar, or a cut rectangle instead of a full plate — we will say so before you order.

Pipe and tube for the same exchanger can be quoted with the plate or discs, with sizes confirmed per enquiry from Mumbai stock. See 625 pipe and tube in Chennai. Dispatch into the estate is agreed with you and your transporter when the order is placed. We do not give a fixed transit time, because it depends on the carrier and the route.

Can you punch 625 circles for an Ambattur baffle or blank list?

Yes. Circles from about 30 mm to 300 mm are punched in-house, and larger circles or tube sheets are cut to your drawing. Each piece keeps the parent-plate heat number. Send the diameters, thickness and quantity.

Can you deliver Inconel 625 into Ambattur Industrial Estate?

Yes. We send 625 plate, discs, bar and, where confirmed, pipe into Ambattur Industrial Estate and to nearby shops in Guindy, Thirumudivakkam and Vanagaram, supplied from Mumbai stock. We provide direct door delivery to your company in Chennai. We do not have an office in the estate.

For an Ambattur job, should we buy 625 plate, discs or bar?

Buy plate or sheet when you are making a tube sheet, shell, pad or cover. Buy discs or circles when the starting shape is round, such as a baffle or a blank; circles from about 30 mm to 300 mm are punched in-house, and larger ones are cut to drawing. Buy bar when the part will be turned or milled from a diameter. Send the drawing if you are unsure.

Inconel 625 or Hastelloy C276 for an Ambattur exchanger?

625 is the usual choice where strength, weldability and chloride or seawater resistance matter. C276 is the step up when the process side carries mixed acids, wet chlorine or a more aggressive chloride mix. Share the medium and temperature and we will help you compare; see C276 plate in Chennai if the duty points that way.

What should the inspector check on a 625 delivery to Ambattur?

The EN 10204 3.1 mill test certificate, the UNS number N06625, the ASTM grade or condition, and the heat number marked on each piece. Email sales@ganeshmetals.com or call +91 22 6636 2372 if you need those details listed before the material leaves Mumbai.
