Seamless ASTM A790 2507 Cold Rolled Duplex Steel Pipe
Duplex Steel Pipe:
Duplex steels have a mixed microstructure with about equal proportions of ferrite and austenite.
The chemical composition based on high contents of Cr and Mo improves intergranular and pitting corrosion resistance, respectively.
