About Super Duplex Steel Ferralium 255 Sheet

Super Duplex stainless steel Ferralium 255 is an alloy composed of high chromium (25%), nickel (3.7%) and molybdenum (3.7%). It also contains small amounts of phosphorus, silicon and nitrogen, making it incredibly strong with good corrosion resistance to seawater and chloride environments. It is often used in applications such as boat hulls, chemical processing, food production equipment, flue gas desulphurisation plants, etc.

Superior Mechanical and Corrosion Resistance

Ferralium 255 Super Duplex Steel Sheet brings together high tensile (min. 790 MPa) and yield strengths with outstanding resistance to pitting, crevice, and stress corrosion. Its duplex structure-featuring elevated chromium, nickel, and molybdenum content-ensures durability even in aggressive environments, making it a trusted component in critical industrial sectors.

Versatile Applications and Tailored Solutions

This sheet is customizable in width, length, and thickness, meeting specific application needs across industries. Its versatile nature lends itself to use in marine, chemical, construction, and oil & gas sectors, among others. Available edge conditions, surfaces, and coatings enable precise configuration for every project requirement.

FAQ's of Super Duplex Steel Ferralium 255 Sheet:

Q: How is Super Duplex Steel Ferralium 255 Sheet typically used?

A: Ferralium 255 sheets are widely used in demanding applications requiring high strength and corrosion resistance, such as chemical processing plants, marine engineering, desalination systems, oil and gas facilities, and pulp & paper industries. Their durability and flexibility make them suitable for both structural and process equipment.

Q: What are the main benefits of choosing Ferralium 255 over other stainless steel grades?

A: Ferralium 255 offers a unique combination of high yield (min. 550 MPa) and tensile (min. 790 MPa) strengths, excellent corrosion resistance-especially against pitting and stress corrosion-and high impact toughness, even at low temperatures. Its duplex structure allows for better weldability and moderate machinability compared to standard duplex grades.

Q: How can Super Duplex Steel Ferralium 255 Sheets be fabricated and processed?

A: These sheets are known for good formability and can be bent or welded effectively using the right procedures and suitable fillers. They are available in both mill and slit edge conditions, and various surface finishes such as hot rolled, cold rolled, or polished. Moderate machinability enables easier processing compared to other duplex steels.

Q: Where can Ferralium 255 sheets be installed for maximum performance?

A: Optimal performance is achieved in corrosive and high-stress environments such as marine structures, offshore platforms, chemical processing units, and desalination plants. Their corrosion and impact resistance make them reliable for both indoor and harsh outdoor installations.

Q: What surface finishes and protective coatings are available for these sheets?

A: Ferralium 255 sheets are offered with surface finishes including 2B, BA, No.1, No.4, mirror, and brushed as required. While typically uncoated, optional PVC film protection is available for safeguarding surfaces during handling and export, delivered on wooden pallets or boxes according to export standards.
