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.

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.
