Super Duplex 2507 Plates, Sheets, Pipes, Bars & Flanges – UNS S32750

Super Duplex 2507 (UNS S32750) – Stockist, Supplier and Processor in Mumbai Since 1992

Super duplex 2507 (UNS S32750, W.Nr 1.4410) is a highly alloyed duplex stainless steel with about 25% chromium, 7% nickel, 4% molybdenum and high nitrogen. With a pitting resistance equivalent number above 40, it resists pitting and crevice corrosion in warm seawater and chloride brines where 2205 reaches its limit, and offers even higher strength. Ganesh Metals, a stockist, supplier and processor in Mumbai since 1992, supplies super duplex 2507 plate and sheet to ASTM A240 / ASME SA240, bar to ASTM A479 and A276, pipe to A790 and A928, tube to A789, and flanges and forgings to ASTM A182 F53, all with EN 10204 3.1 MTCs and heat-number traceability.

Super duplex is specified for seawater, produced water and brine systems where failure would be costly, often under offshore or desalination project specifications. These projects may call for extra testing such as ferrite count, impact tests or corrosion tests; tell us your specification and we will confirm what certification can be supplied with the material.

Why Choose Super Duplex 2507?

Super duplex 2507 offers very high strength, outstanding resistance to chloride pitting, crevice corrosion and stress-corrosion cracking, and good erosion and fatigue resistance. Its strength allows thinner walls than austenitic grades, saving weight on piping and vessels.

Applications:

Super duplex 2507 is chosen for warm seawater and chloride brines that pit standard duplex and stainless steels.

Oil & Gas: Subsea and topside piping, manifolds and produced-water systems in high-chloride service.
Marine: Seawater firewater and cooling systems, pumps and valves on ships and offshore platforms.
Heat Exchangers: Tubes and shells for seawater coolers and brine heaters in desalination plants.
Chemical Processing: Equipment for chloride-rich process streams, brines and dilute acids.
Pharma Equipment: Process piping and vessels exposed to aggressive chloride cleaning regimes.

Super duplex 2507 is supplied as plates and sheets, round bars, seamless and welded pipes and tubes, flanges, fittings and forgings. Sizes on request – share dimensions, project specification and quantity.

Super Duplex 2507: Specs, Sizes & Equivalents

For 2507 we confirm the mill, the certification and any project-specific testing before quoting, because offshore and desalination specifications differ. Original mill markings stay on every plate and pipe, and export or SEZ consignments are packed in wooden boxes with dispatch identification letters.
