Product Description
Super Duplex 2507 Welded Stainless Steel Pipe
ASTM A789 / A790 2205 / 2507 Duplex Steel Seamless Pipe With Cold Rolled
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, offering greater tensile and yield strength, good ductility, and excellent stress corrosion cracking resistance while helping clients reduce purchase costs without compromising quality.
