Ferralium 255 Strip, Sheet & Plate is a premium super‑duplex stainless steel product renowned for its exceptional strength, corrosion resistance, and versatility. Labdhi Metals, a leading manufacturer, stockist, and exporter, provides these high-performance materials to industries such as marine, oil & gas, petrochemical, chemical processing, power generation, and pulp & paper.
Ferralium 255 (UNS S32550) combines high chromium (24–27%), molybdenum (2.9–3.9%), nickel (4.5–6.5%), nitrogen (0.10–0.25%), and copper (1.5–2.5%), creating a material that resists pitting, crevice corrosion, and stress corrosion cracking even in aggressive environments . Its super-duplex microstructure provides yield strengths nearly twice that of austenitic grades like 316, while maintaining excellent ductility and impact properties
As a manufacturer, Labdhi Metals produces Ferralium 255 strip, sheet, and plate under tight quality controls. They offer a full range in cold-rolled, hot-rolled, and annealed conditions, with thicknesses from 0.15 mm strip up to 120 mm plate, and widths ranging from 250 mm to 3 500 mm . Custom cutting, edge slitting, surface finishes (2B, BA, No.1, No.4, mirror), and fabrications such as clad plates are available.
As a stockist, Labdhi Metals keeps a wide inventory, ensuring fast delivery and flexibility. Standard sizes include cold-rolled sheets (0.5–6.4 mm), hot-rolled (3–10 mm), and plates up to 120 mm. They supply both strips and full-width sheets tailored to customer needs
