About Super Duplex Steel 2507 Sheet

Super Duplex Steel 2507 Sheet is a chromium, molybdenum, and nickel-based alloy with superior strength and corrosion resistance. It contains 25-27% chromium, 6-8% molybdenum, 3.5-5.5% nickel, 1.2% manganese, 0.3% nitrogen, and less than 0.03% sulphur as its primary components. This composition creates an alloy that is highly resistant to pitting corrosion while b

Outstanding Strength and Durability

Super Duplex Steel 2507 Sheet stands out for its exceptional mechanical properties, including a high yield strength of 550 MPa and elongation of 15%. This makes it highly resistant to deformation and suitable for heavy-duty industrial use. Its long service life is further reinforced by excellent resistance to chloride-induced stress corrosion cracking, making it a dependable choice for demanding environments.

Superior Corrosion and Heat Resistance

Thanks to its advanced chemical composition with high levels of chromium, molybdenum, and nitrogen, the 2507 grade offers excellent resistance to pitting, crevice, and general corrosion. It performs well in aggressive conditions, such as marine and chemical processing. With heat resistance up to 300C for short-term service, it maintains strength and structural integrity under harsh operating conditions.

Versatility and Customization

Available in a variety of widths (1000mm - 2500mm), thicknesses (1mm - 50mm), and finishes (2B, BA, No.1, No.4, HL, Mirror), Super Duplex Steel 2507 Sheets can be tailored to specific project requirements. Common dimensions are 2500mm x 1250mm, but custom sizes and surface finishes ensure maximum flexibility for diverse industrial fabrication needs.

FAQ's of Super Duplex Steel 2507 Sheet:

Q: How does Super Duplex Steel 2507 Sheet compare to conventional stainless steels in terms of corrosion resistance?

A: Super Duplex Steel 2507 Sheet offers significantly better resistance to pitting, crevice, and chloride stress corrosion cracking compared to conventional austenitic stainless steels like 304 or 316. Its duplex structure and high alloy content make it ideal for highly corrosive environments, particularly in marine and chemical processing applications.

Q: What are the typical applications for Super Duplex Steel 2507 Sheets?

A: These sheets are commonly used in chemical processing plants, offshore oil and gas platforms, desalination units, heat exchangers, pressure vessels, and other environments where high strength and exceptional corrosion resistance to chlorides are necessary.

Q: Where can Super Duplex Steel 2507 Sheets be supplied from?

A: Super Duplex Steel 2507 Sheets are available from specialized steel manufacturers, exporters, importers, and suppliers worldwide. Custom sizes and finishes can be ordered based on project requirements, often in accordance with ASTM A240, EN 10088-2, and ASME SA240 standards.

Q: What factors should be considered during the welding process of 2507 Sheets?

A: While 2507 sheets offer good weldability, careful control of heat input and interpass temperature is crucial to maintain their excellent corrosion resistance. It is important to use recommended welding techniques and consumables to prevent loss of material properties, especially when fabricating for corrosive environments.

Q: How is the surface finish of Super Duplex 2507 Sheets customized for various applications?

A: Surface finishes such as 2B, BA, No.1, No.4, hairline (HL), and mirror can be specified depending on usage requirements. Custom coatings like pickling or passivation are also available to enhance corrosion protection, or a smooth, uncoated surface can be provided if preferred.

Q: What are the main benefits of using Super Duplex Steel 2507 Sheet in fabrication?

A: Key benefits include high tensile and yield strength, outstanding resistance to various forms of corrosion, good formability and weldability, long service lifespan, and suitability for a range of temperature and chemical exposures. These make 2507 Sheets a reliable choice for critical structural and process equipment.
