Sumer Metal Industries Private Limited, based in India, is both a manufacturer and global exporter of UNS S31803 duplex stainless steel—also known as duplex 2205 or ASTM A240/A182 F51 grade. Their offering includes sheets, plates, and coils that are widely used in demanding sectors such as oil & gas, desalination, chemical processing, marine, and offshore structures. Available in a variety of thicknesses, widths, and finishes, their products meet international standards and customer customizations.

Typical product specifications for UNS S31803 sheet, plate, and coil (as offered by companies including Sumer Metal) include compliance with ASTM A240 / ASME SA240. Thickness ranges from 0.3 mm up to 100 mm or more, with sheet widths reaching 10 mm to 3,000 mm+, depending on configuration. Surface finishes include 2B, 2D, No. 1, BA, No. 4, No. 8 (mirror), and optional textures like hairline, brush, or embossed. Forms delivered include hot‑rolled plates, cold‑rolled sheets, coils, and special configurations such as perforated or chequered plate

UNS S31803, commonly known as Duplex 2205, is a duplex stainless steel alloy that offers a balanced combination of strength and corrosion resistance. Manufactured and exported by Sumer Metal Industries Pvt. Ltd., these sheets, plates, and coils are known for their superior performance in demanding environments, including marine, chemical processing, oil and gas, and desalination industries. The alloy’s duplex microstructure—composed of roughly equal parts austenite and ferrite—gives it enhanced resistance to stress corrosion cracking and exceptional mechanical strength.

SS 904L is a super austenitic stainless steel with low carbon content and high levels of nickel, molybdenum, and copper, giving it outstanding resistance to sulfuric acid, chloride-induced pitting, and stress corrosion cracking. Sumer Metal’s 904L coils exhibit excellent formability, weldability, and durability in harsh and corrosive environments. These coils are available in hot rolled (HR) and cold rolled (CR) forms and are used in fabricating heat exchangers, tanks, piping systems, and structural components.
