    ASTM A789 UNS S31803 Duplex Stainless Steel Seamless Tube For Chemical Process Plant

    ASTM A789 UNS S31803 Duplex Stainless Steel Seamless Tube For Chemical Process Plant


    ASME SA789 S31803 stainless steel tubing provides better pitting and crevice corrosion resistance than 316L or 317L austenitic stainless steel in almost all corrosive media. It also has high corrosion and erosion fatigue properties, as well as lower thermal expansion rates and higher thermal conductivity compared to austenitic stainless steels. The advantage of a duplex structure is that it combines the advantages of ferritic alloys, stress corrosion resistance, crack resistance, and high strength with the ease of manufacture and corrosion resistance of austenitic alloys.
