1.4462 Duplex Steel Pipe S32205 Duplex Steel Pipe Fitting
Duplex stainless steel was developed to combat common corrosion problems encountered with 300 series stainless steels. The "duplex" structure combines favorable qualities of ferritic alloys (stress corrosion cracking resistance and high strength) with those of austenitic alloys (ease of fabrication and corrosion resistance).
UNS32750 super duplex stainless steel pipes offer enhanced corrosion resistance compared to other materials, with greater tensile and yield strength, good ductility, and excellent stress corrosion cracking resistance. These pipes provide cost-effective solutions while maintaining superior quality.
