ASTM A790 SAF2507 Large Diameter Stainless Pipe Higher Yield With Annealing And Pickling
GANYEAH GROUP is specialized in ASTM A790 SAF2507 Large Diameter Stainless Pipe produce . So we know good at duplex steel knowledge . Hope the clients who are choose us can be very assured . And no need worry about our produce ability. We ,GANYEAH GROUP, is worth for your belived .
Most of ASTM A790 SAF2507 Large Diameter Stainless Pipe 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 .

SAF 2507 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.
Welcome everyone who need this kind of pipes contact to me in free . Also GANYEAH can produce stainless steel seam pipes, bright annealed tubes, seam coiled tubing etc . You go ahead one step , we can help you creat more profits than your mind .
