Inconel 625 Discs and Circles in Chennai for Tube-Sheet Blanks and Pads

Inconel 625 Discs and Circles in Chennai for Tube-Sheet Blanks and Pads

Inconel 625 discs and circles for Chennai exchanger and vessel shops, punched in-house from about 30 mm to 300 mm. Fabricators in Ambattur, Thirumudivakkam and Sriperumbudur use these blanks for baffles, nozzle pads, small tube-sheet inserts and cover discs, with the heat number retained on every piece. Larger circles and full tube sheets are cut to your drawing from stock plate — see Inconel 625 plate in Chennai for cut plate, shells and rectangular sizes. Ganesh Metals has been a high-nickel alloy stockist, supplier and processor in Mumbai since 1992.

We provide direct door delivery to your company in Chennai. Discs are punched or cut at our Mumbai shop and supplied from our Mumbai stock to Ambattur, Thirumudivakkam, Guindy, Sriperumbudur or Irungattukottai. Send the diameter, thickness and quantity, or the drawing, and we will confirm what we can punch or cut before quoting.

Inconel 625 discs: grade and specification

Discs and circles are punched or cut from Inconel 625 sheet and plate (UNS N06625, W.Nr 2.4856) to ASTM B443 / ASME SB443. Grade 1 (annealed) is the usual condition for exchanger blanks; Grade 2 (solution annealed) is used when the drawing asks for it.

This page is for round blanks. For rectangular plate, shells and full tube sheets, use the 625 plate in Chennai page. Matching bar and pipe details are on the grade page.

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

Punching range: in-house punched circles from about 30 mm to 300 mm diameter, in the thicknesses we hold as sheet and thin plate. Diameters above that range, and thick discs, are cut to drawing from stock plate, still with the heat number transferred to each piece.

Typical chemistry of the parent plate: Ni 58% min, Cr 20–23%, Mo 8–10%, Nb+Ta 3.15–4.15%. Density about 8.44 g/cm³. Mechanical properties follow the parent plate; they are reported on the EN 10204 3.1 MTC for that heat.

Each disc is marked so the heat number of the parent sheet or plate is not lost after punching. That is what inspectors look for on a bag of baffles or pads.

Welding and overlay blanks in 625 are commonly joined with ERNiCrMo-3 filler, the same family used on 625 plate work.

625 discs: what we punch and what we cut

Most Ambattur and Sriperumbudur orders are punched discs in the 30–300 mm range for baffles, nozzle pads and small blanks. When the diameter or thickness is outside that punching range, we cut the circle from stock plate to your drawing. Either way, you get a round blank with the heat number on it, not a square offcut you have to trim on site. Estimate weights with the metal weight calculator.

Where 625 discs are used in Chennai shops

Heat-exchanger shops in Ambattur Industrial Estate: punched 625 discs for baffles, support plates and small tube-sheet inserts.

Bundle and shell shops in Thirumudivakkam and Guindy: circles for cover discs and wear pads on chloride or seawater exchangers.

Vessel builders in Sriperumbudur and Irungattukottai: nozzle-reinforcement pads and manway blanks punched or cut as circles.

Maintenance teams: a small bag of heat-numbered pads or blanks, rather than a full plate for one repair.

Why Chennai exchanger shops order 625 discs 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.

The heat number is transferred to every punched or cut disc, so a bag of baffles still traces to the parent plate.

You order the diameters you need; the skeleton stays in Mumbai instead of in your scrap bin.

Grade 1 or Grade 2 is read off the parent-plate MTC against your order before punching starts.
