S31803 Tube,ASME SA789 ASTM A789 2205 Duplex Stainless Steel Seamless Tube
S31803 Pipe SA 789 A789 S31803 Duplex Tube A790 SA790 S31803 Pipe
Alloy ASME SA789 S31803 Stainless Steel Pipe provides pitting and crevice corrosion resistance superior to316L 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 and higher thermal conductivity than austenitic.The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy stress corrosion cracking resistance and high strength with austenitic alloy ease of fabrication and corrosion resistance.
