Duplex stainless steel 2205 combine the best attributes of both austenitic and ferritic stainless steels and provide high strength/ductility with good corrosion resistance to corrosion (including stress corrosion cracking). This gives them a significant advantage over 316L and 317L stainless steels. The chemical component of Duplex stainless steel 2205 : C≤0.030 Mn≤2.00 Si≤1.00 p≤0.030 S≤0.020 Cr 21.0～23.0 Ni 4.5～6.5 Mo2.5～3.5 N0.08～0.20 The Mechanical property: Tensile Strength ≥625MPA Yield Strength ≥450MPA Elongation ≥25 Hardness ≤290HB Application Area Chemical processing, transport and storage, Oil and Gas exploration and processing equipment, Marine and other high chloride environments, Pulp and paper digesters, liquor tanks and paper machines.
