2507 / 1.4410 is a super duplex stainless steel with 25% chromium, 4% molybdenum, 7% nickel . This kind of pipes always purchased by the clients who are require exceptional strength and corrosion resistance .
The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion. And the high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.
Most of 2507 / 1.4410 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 .
