Super Duplex 2507 Plate in Chennai for Seawater and Desalination Duty
Super Duplex 2507 Plate in Chennai for Seawater and Desalination Duty
Super Duplex 2507 plate and sheet for seawater and desalination work on the north Chennai coast. Fabricators serving Ennore, Kattupalli and coastal desalination trains specify 2507 when the chloride level, temperature or pressure is beyond Duplex 2205, and when the part must resist pitting and crevice attack in flowing or stagnant seawater. Ganesh Metals supplies 2507 plate cut to size and has been a stockist, supplier and processor of high-nickel alloys and duplex grades in Mumbai since 1992.
We provide direct door delivery to your company in Chennai. 2507 plate is cut and packed at our Mumbai shop and supplied from our Mumbai stock to Ennore, Kattupalli, Minjur, Ambattur or the coastal desalination belt. Tell us the seawater conditions and the design code, and we will confirm 2507 is the right grade before quoting.
Super Duplex 2507 plate specifications
Super Duplex 2507 (UNS S32750, W.Nr 1.4410): plate and sheet ASTM A240 / ASME SA240, usually purchased to the S32750 chemistry.
Matching forms: bar ASTM A276 / A479, seamless and welded pipe ASTM A790 / A928.
Pipe, tube and flanges: sizes confirmed per enquiry, from Mumbai stock.
2507 versus 2205: 2507 has higher chromium, molybdenum and nitrogen, which raises resistance to seawater pitting and crevice attack. Use Duplex 2205 plate in Chennai for everyday chloride and process-water equipment; step up to 2507 when the duty is seawater, higher temperature or a tighter pitting requirement on the drawing.
When a high-nickel or titanium grade is specified instead: Titanium Grade 2 and Monel 400 are also used for seawater. 2507 is the usual Super Duplex plate choice when the drawing stays in the duplex family and needs higher strength than those alloys in the annealed condition.
Typical chemistry: Cr 24.0–26.0%, Ni 6.0–8.0%, Mo 3.0–5.0%, N 0.24–0.32%, C 0.030% max, iron balance. Density about 7.80 g/cm³.
Minimum properties, ASTM A240 UNS S32750 plate: tensile 800 MPa, yield 550 MPa, elongation 15%.

2507 plate and sheet: how it is supplied
Seawater and desalination jobs usually need 2507 cut to vessel, filter and header sizes rather than a full mill plate. We cut plate and sheet to your list or drawing, punch circles for blanks and manway discs, and keep the heat number on every piece. Estimate weights with the metal weight calculator.

Where 2507 plate is used around Chennai
Seawater intake and cooling systems around Ennore: 2507 plate for intake screens, water boxes and chloride-rich cooling-water vessels.
Marine and port fabrication near Kattupalli: 2507 for seawater headers, strainers and structural plate in splash and immersed service.
Desalination equipment on the coastal belt: 2507 plate for high-chloride vessels, filters and piping components built to the project specification.
Coastal process plants with seawater or brine utility systems: 2507 where 2205 would be under-specified.
Fabrication shops in Ambattur building this equipment: 2507 plate cut to shells, covers and tube-sheet sizes.
Why Chennai seawater fabricators order 2507 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.
2507 and 2205 offcuts look similar, so each lot is grade-checked against the MTC before dispatch.
Plate is cut to your nesting list, so a seawater vessel does not have to start from a full mill sheet.
If the duty is better served by titanium Grade 2 or Monel 400, we will say so rather than defaulting to 2507.












FAQs — Chennai
Do you supply Super Duplex 2507 plate to Ennore and Kattupalli?
Yes. We send 2507 plate and sheet to Ennore, Kattupalli, Minjur, Ambattur and the coastal desalination belt, 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.
Super Duplex 2507 or Duplex 2205 for a seawater line?
2205 is often enough for moderate chlorides and process water. 2507 is the usual step up for seawater, higher temperature or a tighter pitting requirement. Send the chloride level, temperature and the specification on your drawing and we will help you compare.
2507 or Titanium Grade 2 for desalination plate?
Both are used. Grade 2 is lighter and resists stagnant seawater extremely well; 2507 is stronger in the annealed condition and is often chosen for structural seawater plate. Share the conditions and we will help you compare. See also Titanium Grade 2 sheet in Chennai.
Will 2507 plate come with a 3.1 certificate?
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.
