ASTM A789 tus qauv specification siv rau zus tau tej cov seamless thiab welded duplex stainless hlau kav. UNS S32750 stainless hlau yeeb nkab yog super duplex stainless hlau uas muaj txog 25% chromium, 7% nickel, 4% molybdenum thiab 0.3% nitrogen. Nws muaj qhov zoo formability thiab tuaj yeem ua tiav los ntawm kev kub kub thiab txias sib sau.
Piv nrog rau 300 series austenitic stainless hlau los yog ib txwm duplex alloys, S32750 duplex stainless hlau tubing tau txhim khu kev tiv thaiv rau pitting thiab crevice corrosion, thiab duplex qauv muab S32750 zoo heev tiv thaiv chloride kev nyuaj siab corrosion cracking.
S32750 super duplex yeeb nkab yog dav siv nyob rau hauv lub sij hawm uas yuav tsum tau muaj zog thiab siab corrosion kuj, xws li submarine pipelines, shipbuilding thiab offshore gas teb ntau lawm.
Kev siv EN 1.4410 stainless hlau seamless yeeb nkab yuav tsum raug txwv rau cov ntawv thov hauv qab 6000 degree F (3316 degree). Ntev ntev raug rau qhov kub thiab txias yuav txo tau nws cov toughness thiab corrosion kuj.
