Stainless Steel Round Pipe Polished SS Tube Duplex 2205 With Stock
Stainless Steel Round Pipe polished SS Tube Duplex 2205 with stock
Stainless steel is an alloy of Iron with a minimum of 10.5%
Chromium. Chromium produces a thin layer of oxide on the surface of
the steel known as the passive layer. This prevents any further
corrosion of the surface. Increasing the amount of Chromium gives
an increased resistance to corrosion.
Stainless steel also contains varying amounts of Carbon, Silicon
and Manganese. Other elements such as Nickel and Molybdenum may be
added to impart other useful properties such as enhanced
formability and increased corrosion resistance.

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 .
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 .
