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).

UNS S32750 super duplex stainless steel pipes offer enhanced corrosion resistance compared to other materials, with greater tensile and yield strength, good ductility, and excellent stress corrosion cracking resistance while helping reduce purchase costs without compromising quality.
