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 .
