Stainless Steel Alloy 2507 Duplex 2507

Duplex 2507. is a commonly used super duplex stainless steel. Also sold as Alloy 2507. this alloy is used in situations where exceptional strength and corrosion resistance are in demand. Some of the applications and industries that utilize Duplex 2507 include:

• Chemical process industries
• Heat exchangers, vessels, and piping
• Desalination plants and other saltwater applications
• Power industry FGD systems
• Offshore platforms including fire-fighting systems

The reason Duplex 2507 is utilized is due to its unique properties. On top of its basic corrosion resistance and strength, Duplex 2507 also provides:

• Extreme resistance to uniform corrosion
• Good resistance to inorganic acids/chlorides
• Works with dilute hydrochloric acid
• Improved machinability and weldability
• High impact strength

To be considered Duplex 2507. an alloy it must contain a number of different chemical components including:

• Fe Balanced
• Cr 25%
• Ni 7%
• Mo 4%
• N .27%
• C 0.020%

Yuze Metal offers a wide range of forms and sizes of Duplex 2507. all of which meet industry standards such as ASTM, ASME, EURONORM, and AFNOR.
