Duplex F61 (UNS S32550), also known commercially as Ferralium 255, is a super‑duplex stainless steel grade engineered for extremely corrosive conditions. Featuring a balanced austenitic‑ferritic microstructure, F61 delivers exceptional strength, toughness, and resistance to chloride‑induced pitting, crevice corrosion, and stress corrosion cracking. These characteristics make it ideal for critical service applications such as offshore oil & gas, chemical processing, petrochemicals, desalination, and marine environments.
As a manufacturer, supplier, and exporter, Sumer Metal Industries Pvt. Ltd. offers Duplex F60 in a full portfolio of product forms: sheets, heavy plates, and coils. Thicknesses typically range from thin coil gauge (~0.25 mm) up to structural plate (~100 mm+). Available finishes include 2B, 2D, polished, brushed, and pickled. International certificates (EN 10204 3.1/3.2, ISO 9001, NACE MR0175) and test reports are provided per customer requirements.
As a leading manufacturer, supplier, and exporter, Sumer Metal Industries Pvt. Ltd. provides Duplex F61 in the form of sheets, heavy plates, and coils, produced to ASTM A240 / ASME SA240 standards. The product range spans thicknesses from around 1 mm to 100 mm+, and widths up to 3 m, depending on client requirements. Typical surface finishes offered include 2B, No. 1, BA, mirror-polished, and brushed. All shipments are accompanied by EN 10204 3.1 / 3.2 certification, PMI reports, and NACE MR0175 compliance where needed.
Duplex F61 is commonly available in flat-rolled forms such as sheets, plates, and coils. These forms are widely used in fabrications requiring high strength, excellent pitting and crevice corrosion resistance, and long-term performance. Sheets and plates are often used in the manufacturing of pressure vessels, tanks, heat exchangers, and structural components. Coils are typically used in automated manufacturing processes for piping, tubing, and custom-cut parts.

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.
