Product Details
2205 Duplex stainless steel (UNS S32205 formerly known as UNS S31803 and commonly known as “alloy 2205”) has a mixed microstructure of austenite and ferrite, and is a two-phase alloy based on the Fe-Cr-Ni series. Alloy 2205 material has lower nickel and molybdenum contents than austenitic stainless steel and have similar corrosion resistance. Because the price of Ni and Mo is relatively high, duplex stainless steel 2205 is often regarded as a cost-effective alternative to austenitic stainless steel.
Compared with the conventional 300 series stainless steel, the special advantages of duplex 2205 stainless steel are strength (about twice that of austenitic stainless steel), and excellent resistance to chloride SCC and pitting corrosion. High yield strength has sufficient pressure and load capacity, and thin-wall materials can be made to greatly reduce weight.
Shape: Round, Square, Rectangular, Slot, Oval, etc
Outer Diameter:
1) Round pipe: 8mm to 680 mm
2) Square pipe: 10x10mm to 300x300mm
3) Rectangular pipe: 10x20mm to 120x180mm
Thickness:
1) Seamless pipe: 0.6mm – 30mm
2) Welded pipe: 0.5mm – 25mm
Application: Chemical Process, Petrochemical, Oil & Gas, Pharmaceutical, Geothermal, Sea Water, Water Desalination, LNG (Liquefied Natural Gas), Biomass, Mining, Utilities, Nuclear Power. Solar Power, ect
