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 provide enhanced corrosion resistance compared to other materials, with greater tensile and yield strength, good ductility, and excellent stress corrosion cracking resistance. These pipes help reduce purchase costs while maintaining quality standards.
High corrosion resistance applications (offshore industry, etc.)
