Detailed Product Description

ASTM A790 S32750 Duplex Steel Seamless Pipe

 

 

ASTM A790: Standard for seamless ferritic/austenitic (duplex) stainless steel pipe, covering chemical, mechanical and testing requirements. Ensures suitability for corrosive environments and high-pressure applications.


UNS S32750 (Super Duplex 2507) Super duplex stainless steel with a duplex microstructure (austenite + ferrite) offers increased strength and corrosion resistance compared to standard duplex grades such as 2205/S32205.

 

Superior strength-to-weight ratio compared to austenitic steels. Excellent resistance to chlorides, acids and sour environments (H₂S). Long service life in extreme conditions and reduced maintenance costs.
