Norwich Steel & Engineering Co. is a known exporter of Duplex Steel UNS S32205 / Duplex Steel UNS S31803 Tubes, which maintain good weldability in their thickest sections. Duplex UNS S32205 Tubes has excellent resistance to localized corrosion including inter - granular, pitting and crevice corrosion. Duplex Steel UNS S31803 Seamless Tubesare apt replacements to austenitic grades, especially in premature failure environments and marine environments. Duplex UNS S32205 Welded Tubes has good weldability in thick plates, and may be successfully machined by conventional methods. Exceptional contemplation is desirable to recompense for a greater factor of thermal development in Duplex Steel UNS S31803 EFW Tubes to evade distortion and warping. Duplex Steel UNS S32205 ERW Tubes has high strength, good resistance to sulfide stress corrosion, and high resistance to pitting and crevice to corrosion. The corrosion resistance of Duplex Steel UNS S31803 Round Tubeis greater than that for the most commonly used grades of stainless steels. Duplex Steel UNS S32205 Square Tubes is readily weldable using many of the standard electric arc welding processes.
