S32205 / S31803 Big Size Duplex Steel Pipe With Annealed & Pickled Surface For Chemical Industry

DP-1-0032

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 ) .
