duplex 2205 Steel Chemical Composition (in weight %)

Corrosion resistance
Uniform corrosion Uniform corrosion is characterised by a uniform attack on the steel surface that has come into contact with a corrosive medium. The corrosion resistance is generally considered good if the corrosion attack is less than 0,1 mm/year. Due to the high content of chromium duplex 2205 pipe offers excellent corrosion resistance in many media.

Intercrystalline corrosion
The duplex microstructure and the low carbon content gives 2205 duplex stainless steel pipe very good resistance to intercrystalline corrosion. The composition of the steel ensures that austenite is reformed in the heat-affected zone after welding. The risk of undesirable precipitation of carbides and nitrides in the grain boundaries is thus minimized.

duplex 2205 stainless steel is composed of two different crystal structures, ferrite and austenite. This special structure gives it good corrosion resistance and mechanical properties. Multiple processes are required on production process of duplex 2205 pipe,such as smelting, rolling, heat treatment, etc., all of which play a crucial role in improving the performance of the steel pipe.
duplex 2205 pipe is widely used in the fields of petroleum and chemical industry. Due to its high strength and good corrosion resistance, 2205 stainless steel pipe can be used to manufacture various pressure vessels, pipelines, storage tanks, and reactors. Among these devices, duplex stainless steel 2205 steel pipes can effectively resist the corrosion of various chemicals, thereby ensuring the long-term stable operation of the equipment.
