ASTM A790 2205 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 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 .
