Product Description
Duplex Stainless Steel Tubes
UNS S31803, S32205, S32750, 1.4410, 1.4462 Duplex Stainless Steel Tube
Product Overview
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).
Key Benefits
UNS32750 super duplex stainless steel pipes offer improved corrosion resistance compared to other materials, with greater tensile and yield strength, good ductility, and excellent stress corrosion cracking resistance. These tubes provide cost savings while maintaining superior quality.
