Sumer Metal Industries Pvt. Ltd. is positioned as a leading manufacturer, supplier, and exporter of UNS S32550 (Super Duplex/F61) in sheet, plate, and coil forms. Products are produced per ASTM A240 / ASME SA240 and related API standards, in thicknesses from ~1 mm up to ~200 mm and widths up to ~3000 mm. Offered finishes include hot‑rolled (HR), cold‑rolled (CR) with surface options like 2B, 2D, BA (No. 8), and satin finishes. Custom shapes—plain sheets, perforated, chequered plates, shim sheets, coils—are available with full mill test certificates and export-grade packaging.

UNS S32550 is categorized as super duplex due to its superior strength and corrosion resistance compared to conventional duplex grades like S32205. Its alloy design makes it ideal for corrosive environments—oil & gas, offshore structures, chemical and acid processing, seawater handling, and pollution control equipment. The alloy’s robustness, even handling acidic media such as sulfuric, phosphoric, and nitric acids, suits it for pulp‑and‑paper digesters, storage tanks, and harsh marine deploymentsl.

UNS S32550, also known as Ferralium® 255 or Super Duplex F61, is a high-performance stainless steel alloy developed for demanding industrial applications. With a microstructure that combines ferrite and austenite, this super duplex grade provides significantly higher strength and corrosion resistance than conventional austenitic stainless steels like 304 or 316. The addition of elements like chromium, molybdenum, nitrogen, and copper gives this alloy exceptional resistance to chloride-induced corrosion, making it an ideal choice for aggressive environments such as offshore oil and gas, desalination, and chemical processing.

UNS S32550 sheets, plates, and coils are manufactured according to ASTM A240 / ASME SA240 standards and are available in a wide range of thicknesses and surface finishes. These products are offered by Sumer Metal Industries Private Limited, a reputable manufacturer, supplier, and exporter known for delivering high-quality stainless steel materials with precision and global compliance. The material can be supplied in hot-rolled or cold-rolled condition, in standard mill finishes like 2B, No.1, No.4, or polished variants, and is suitable for welding, machining, and fabrication.
