ASTM A790 2507 duplex steel pickling tube are always purchased by the clients who need high corrosion tubes .
Compared to stainless steel tubes , duplex steel tubes have more higher corrosion ability . They can be used in sea industry .
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 .
