Product Description
S32750 2507 1.4410 Super Duplex Steel Pipe
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).
UNS S32750 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 pipes provide cost-effective solutions while maintaining high quality standards.
