Most of 2507 duplex steel pipes are produced by cold drawn method . The alloy has higher yield strength and lowerductility than austenitic steels so fabricators may fd that higher forming forces , increased radius of bending , and increased allowance for spring back 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 mmediatelvy bv a rapid air or water auench, To obtain maximum corrosion resistance. heat treated products should be pickled and rinsed .
