What grades are included in duplex stainless steel? Thank you! This post was last edited by Lan Meng on 2009-3-28 at 13:54.]
China and other countries **Types of duplex steels (common types): China, United States, Japan, Europe. Duplex steels: 00Cr18Ni5Mo3Si2, S31500, 3RE60; 00Cr22Ni5Mo3N, S31803, 329J3L1, SAF2205; 00Cr25Ni6Mo2N, 329J1L1R-4; 00Cr25Ni7Mo3N, S31260, 329J4L, SAF2507; 00Cr25Ni6Mo3CuN, S32550
European standards: Duplex steels: S31803, S32205; corresponding welding materials: E 2209. Super duplex steels: S32550, S32750, S32760; corresponding welding materials: E 2553
Duplex steel: S31803, S32205; Super duplex steel: S32550, S32750, S32760
Duplex stainless steels: SAF 2205, S31803/S32205, SAF 2507, S32750, SAF 2304, S32304, 3RE60, S31500, SAF 2707HD, S32707; Ultra-ultra duplex steels
Duplex stainless steels can be roughly divided into four categories: The first category is the low-alloy type, represented by the grade UNSS32304； In the second category, there are alloy types, with the representative grade being UNSS31803 ； The third category is the high-alloy type, represented by the grade UNSS32550 ； The fourth category consists of super duplex stainless steels, with the representative grade being UNSS32750
There are quite a number of grades for duplex steel; the commonly used ones are grades 2205 and 2507
Is duplex stainless steel 1803 the same as 2205?
