Duplex steel F51 F53 F55 ball valve material feature
Compared with austenitic stainless steel, Duplex steel F51 F53 F55 ball valve strength is higher and its resistance to intercrystalline corrosion and chloride stress corrosion is improved obviously. Duplex steel F51 F53 F55 ball valve has excellent corrosion resistance and is also a kind of nickel stainless steel.
In corrosion resistance, especially the medium environment is more harsh (such as seawater, chloride ion content is higher) under the conditions, Duplex steel F51 F53 F55 ball valve resistance pitting corrosion, crevice corrosion, stress corrosion and corrosion fatigue performance is obviously better than ordinary austenitic stainless steel, can be comparable with high alloy austenitic stainless steel.
