The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy ( stress corrosion cracking resistance and high strength ) with those of an austenitic alloy ( ease of fabrication and corrosion resistance ) .
Advantages:
Duplex stainless steel is acknowledged as a very good material which has been mostly utilized in transportation pipelines of meals processing, beverage industry, brewing industry etc.
Duplex stainless steel pipes serves many superior properties.
