    SAF2205 Duplex Stainless Steel Tube SS Seamless Pipe S31803 For Industry

    SAF2205 Duplex Stainless Steel Tube SS Seamless Pipe S31803 For Industry


    SAF2205 Duplex Stainless Steel Seamless Pipe 22%Cr Duplex Pren ≥34.0 S31803


    SAF 2205 (UNS S31803) 22% chromium duplex stainless steel


    General attributes:


    Duplex stainless steel has an α + γ dual-phase structure, so its performance characteristics are built of austenitic stainless steel and ferritic stainless steel. It is a type of stainless steel with high strength and best corrosion resistance. Generally, in the case of low C content, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N.
    Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, while maintaining the 475 ° C brittleness and high thermal conductivity of ferritic stainless steel, and has superplasticity, etc. Features. Compared with austenitic stainless steel, the yield strength is significantly improved, and the resistance to intergranular corrosion, stress corrosion, corrosion fatigue and abrasion is significantly improved.

    Special specifications are available upon negotiation.


    Performance characteristics:
    1. Excellent resistance to general corrosion and local corrosion, especially stress corrosion resistance, pitting corrosion resistance, crevice corrosion resistance, corrosion fatigue resistance and wear resistance etc.
    2. Good solderability
    3. Good comprehensive mechanical properties
    4. Good resistance to intergranular corrosion
    5. High cost performance and long service life


    Application fields are:


    2205 duplex stainless steel pipe is defined as smelting and manufacturing of stainless steel in which the ferrite phase and austenite are 50% each in comparison with the solidified structure. The actual comparative example is that ferrite accounts for 45-55%, and the corresponding austenite accounts for 55-45%. The excellent performance of 2205 duplex stainless steel is ensured by a proper proportion of the two-phase structure.


    2205 duplex stainless steel pipe has excellent mechanical properties and corrosion resistance, as well as good weldability, and has a wide range of uses in the oil and gas industry, marine engineering, chemical industry and other industries. The oil and gas industry uses duplex stainless steel materials to lay oil and gas pipelines with a length of more than 850Km, most of which are 2205 duplex stainless steel seamless steel pipes (also some are S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes); Due to the strong corrosiveness of the natural gas medium, the high-pressure pipelines are made of 2205 duplex stainless steel.

    Delivery form:Sheet, strip, bar, pipe (welded and seamless pipe), wire, forging, light rod, flange, welding
