Welding ASTM A789 Super Duplex 2507 Stainless Steel Coils
Super Duplex 2507 Stainless Steel Coiled Tubings
Tiptop is one of the large supplier for high quality super duplex steel pipes & tubes, super duplex steel UNS S32750 welded pipes, super duplex pipe suppliers, 2507 super duplex rectangular welded pipes, super duplex S32760 ERW Pipes exporter, super duplex welded pipes and 2507 super duplex steel EFW Tubing in China. Super Duplex has a higher chromium and molybdenum content which gives the super duplex greater corrosion resistance than other standard duplex grades.
Super Duplex Steel have the benefit as it counterpart – it has lower alloying costs when compared with austenitic grades and ferritic. Also it has Great tensile and yield strength. Have good toughness and ductility. Ferritic/Austenitic Super Duplex 2507 Seamless Tubing and 2507 Super Duplex Steel EFW Tubing is used in gas and oil industry, on offshore platforms, chemical processing equipment pressure vessels and boilers, in heat exchangers.
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%
Tiptop offers a wide range of forms and sizes of Duplex 2507, all of which meet industry standards such as ASTM, ASME, EURONORM.
