 6 Inch UNS S31803 F51 Duplex Steel Pipe Cold Rolled , 1.4410

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 ) .
