410 super duplex sheet 1.4410 1.4501 coil
Duplex UNS S32750 coils have very low corrosion rates under very high corrosive conditions.
Especially in chloride-rich environments and other sour environments, ASTM A240 UNS S32750 steel plate outperforms other types of steel. In particular, compared with UNS S32205 (NAS329J3L, SUS329J3L) and UNS S32506 (NAS64, SUS329J4L), NAS74N has better localized corrosion resistance. Therefore, the NAS74N is used in harsh environments such as chemical plants and desalination plants. The high chromium and molybdenum content of ASTM A240 UNS S32750 sheet makes it extremely resistant to uniform corrosion by organic acids such as acetic and formic acids. It also has excellent resistance to inorganic acids, especially those containing chlorides.
