Stainless Steel 446 Round Bar Manufacturer, Stainless Steel 446 Round Bar, Stainless Steel 446 Round Bar in India, Stainless Steel 446 Round Bar in Mumbai
Ferralium 255 Tube & Pipe is a highly advanced super duplex stainless steel product engineered to perform in some of the most corrosive and high-pressure environments. Known for its exceptional mechanical strength, superior corrosion resistance, and excellent durability, Ferralium 255 is ideally suited for industries such as chemical processing, marine, offshore oil and gas, desalination, and power generation. Labdhi Metals, a trusted manufacturer, stockist, and exporter, provides top-grade Ferralium 255 tubes and pipes that meet international standards and demanding industry requirements.
Ferralium 255 (UNS S32550) is a super duplex alloy that contains elevated levels of chromium (24–27%), molybdenum (2.9–3.9%), nickel (4.5–6.5%), copper (1.5–2.5%), and nitrogen (0.10–0.25%). This unique composition gives it an excellent pitting resistance equivalent number (PREN > 40), which translates into superior resistance against localized corrosion such as pitting and crevice corrosion, especially in chloride-containing environments. The microstructure of Ferralium 255 offers nearly double the yield strength of standard austenitic stainless steels like 316L, while retaining good ductility and impact resistance.
As a dedicated manufacturer, Labdhi Metals fabricates Ferralium 255 tubes and pipes using high-precision manufacturing processes such as seamless extrusion and welded fabrication. These pipes and tubes are supplied in a variety of forms including seamless, ERW, welded, and fabricated, with strict dimensional tolerances and surface finishes. Products are thoroughly tested for pressure, mechanical strength, and corrosion resistance to ensure flawless performance in critical applications.
As a well-equipped stockist, Labdhi Metals maintains a comprehensive inventory of Ferralium 255 pipes and tubes in a wide range of sizes, thicknesses, and lengths. Their ready stock includes both metric and imperial sizes, suitable for structural, mechanical, and pressure applications. They also offer custom cutting, end finishing (plain, bevel, threaded), and surface treatments such as pickling and passivation.
