ASTM A790 Big Duplex Steel Pipe 6000mm Stainless Seamless Cold Rolled Pipe 

 

 

Most of 2507 duplex steel pipes are produced by cold drawn method . The alloy has higher yield

strength and lower ductility than austenitic steels so fabricators may fid that higher forming forces , increased radius of bending , and increased allowance for springback are necessary . Deep drawing , stretch forming , and similar processes are more difficult to perform on 2507 than on an austenitic

stainless steel . When forming requires more than 10% cold deformation , a solution anneal and quench

are recommended . And finished cold drawn duplex steel pipe , manufacturer should be solution annealed and quenched . The minimum annealing tempeture is 19250F . Annealing should be followed immediately by a rapid air or water quench. To obtain maximum corrosion resistance, heat treated products should be pickled and rinsed .
