3 / 4 Inch UNS S32750 / S32760 Duplex Stainless Steel Tube With
Cold Rolled
Duplex Stainless Steel Tube Application
Duplex stainless steel is a very useful metal that is used the
world over. It gets its name from the fact that it consists of two
different grades of metal.
Essentially, Duplex is a Fe-Ni-Cr alloy that has a two-phase
ferritic-austenitic stainless-steel microstructure when it is at
room temperature.
Duplex Stainless Steel Tube Contents
Duplex steels are characterised by high chromium (19–28%) and
molybdenum (up to 5%) and lower nickel contents than austenitic
stainless steels. The most used duplex stainless steels are the
2205 (22% Chromium, 5% Nickel) and the 2507 (25% Chromium, 7%
Nickel); 2507 is known as “super duplex” due to its higher
resistance to corrosion.

good performance
Super duplex Stainless Steel is a highly alloyed , good performance
duplex steel with a pitting resistance . Super Duplex offers good
resistance to pitting and crevice corrosion . It is suited for use
in aggressive environments . It also has good resistance to stress
corrosion cracking in chloride and sour environments . And it has
good resistance to erosion corrosion and corrosion fatigue .
improved strength
Super duplex stainless such as duplex is a mixed microstructure of
austenite and ferrite which has improved strength over ferritic and
austenitic steel grades . The main difference is super duplex has a
higher molybdenum and chromium content which gives the material
greater corrosion resistance .
Super duplex has the same benefits as its counterpart - it has
lower production costs when compared with similar ferritic and
austenitic grades and due to the materials increased tensile and
yield strength , in many cases this gives the purchaser the
welcomed option of purchasing smaller thicknesses without the need
to compromise on quality and performance .
