Performance:

Compared with austenite, it has lower coefficient of thermal expansion and higher thermal conductivity.The higher compression strength.Designers can reduce its weight compared to 316L and 317L.It is especially suitable for temperatures in the range of -50 °F/+600°F, and can also be used at lower temperatures under severe restrictions (especially for welded structures).

2205 duplex stainless steel is widely used in Petroleum and natural gas industrial equipment;Offshore platforms, heat exchangers, underwater equipment and fire fighting equipment;Chemical processing industry, utensils and plumbing industry;Desalination, high pressure RO equipment and submarine pipelines;Energy industry such as power plant desulfurization denitrification FGD system, industrial washing system, absorption tower;Mechanical parts (high strength, corrosion resistance, wear resistance parts).
