Corrosion Resistance UNS S31803 Duplex Stainless Steel Tubings Pipes
Duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels .
Duplex describes a family of stainless steels that are neither fully austenitic , like 304 stainless , nor purely ferritic , like 430 stainless . 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 ) .
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.
