Product Description
ASTM A789 S31803/2205 Duplex Steel Tube 6000MM SMLS Tubing
Duplex Steel Tube:
Duplex stainless steel offers excellent resistance to corrosion and high mechanical strength.
The high corrosion resistance of duplex stainless steel ensures significantly more uptime than carbon steels and conventional stainless steels, while the mechanical strength allows for lighter constructions, a more compact system design, and less welding.
