Product Detail
Duplex Steel UNS S31803 Pipes demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments. Duplex Steel UNS S31803 Tubes generally has a higher corrosion resistance compared to the austenite steels.
Moreover, the two-phase microstructure guarantees higher resistance to pitting and stress corrosion cracking in comparison with conventional stainless steels.
