F53 (UNS S32750 / W.Nr. 1.4410)
F53 (UNS S32750 / W.Nr. 1.4410) is a superduplex stainless steel characterized by higher contents of chrome, molybdenium and nickel than standard duplex steels, resulting in increased corrosion resistance. These steels were developed for applications in aggressive chloride environments. They also have high mechanical strength and low thermal expansion due to the duplex structure.
