2507 duplex stainless steel pipe
The standard austenitic steels like 304 (1.4301) and ferritic steels like 430 are relatively easy to make and to fabricate. As their names imply, they consist mainly of one phase, austenite or ferrite. Although these types are fine for a wide range of applications, there are some important technical weaknesses in both types.
Super duplex pipes produced under specification ASTM A790, are supplied in a seamless or a welded construction.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. The automatic process used to manufacture Super Duplex Welded Pipe is without the use of a filler metal. The Super Duplex Pipe suppliers recommend using these pipes for applications that are prone to general corrosion resistance
