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).

Using UNS32750 super duplex stainless steel pipes provides enhanced corrosion resistance compared to other materials. These pipes offer greater tensile and yield strength, excellent ductility, and superior stress corrosion cracking resistance, while helping clients reduce purchase costs without compromising quality.
