ASTM A790 2507 Welded Pipe Duplex Steel Tube
Super duplex 2507 welded stainless steel pipe manufactured to ASTM A789/A790 standards with cold rolling process.
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).
UNS32750 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 offer cost-effective solutions while maintaining superior quality.
