Benefits include:
High resistance to pitting and crevice corrosion
Excellent in most caustic environments
Good weldability

High alloy duplex steels,such as S31803/S32205, are generally more difficult to machine than conventional austenitic stainless steels such as17-12-2.5

Super Duplex Alloy UNS S32760 (F55 / 1.4501) has excellent corrosion resistance to a wide variety of media, with outstanding resistance to pitting

Super duplex stainless such as duplex is a mixed microstructure of austenite and ferrite which has improved strength over ferritic and austenitic .

Duplex 2205 Erw Welding Pipe is used in environments where resistance to general corrosion and chloride stress corrosion cracking is important.

Advantages
a) Superior surface finish
b) Better mechanical property
c) More precise dimension
d) Perfect inspection method and inspection equipmet

Excellent ductility and impact strength at both ambient and sub-zero temperatures.
High resistance to abrasion, erosion and cavitation erosion.
