2205 (UNS S32205) duplex stainless steel has a wide range of applications due to its excellent combination of corrosion resistance, mechanical properties and cost-effectiveness. Some common applications for 2205 duplex stainless steel include:
Offshore and marine environments:
– Offshore oil and gas platforms
– Subsea equipment and pipelines
– Desalination plants and seawater intake systems
– Coastal and port infrastructure (e.g. piers, docks, breakwaters)
Chemical and Petrochemical Processing:
– Containers, tanks and pipes for chemical plants
– Equipment for handling corrosive chemicals and corrosive liquids
– Refineries and petrochemical facilities
Pulp and Paper Industry:
– Digesters, evaporators and other process equipment
– Pipes and valves for pulp and paper mills
Water and wastewater treatment:
– Desalination plant components
– Wastewater treatment equipment
– Drinking water distribution system
Generation:
– Nuclear power plant components
– Coal-fired power plant flue gas desulfurization system
– Geothermal power plant equipment
Building and Structural Applications:
– Building facades and cladding systems
– Bridges, interchanges and other infrastructure
– Urban furniture and design elements
Low and high temperature applications:
– Liquefied Natural Gas (LNG) Facilities
– Petrochemical plants and power generation equipment
– Excellent resistance to pitting, crevice and stress corrosion cracking
– High strength-to-weight ratio, providing design flexibility and weight savings
– Maintains mechanical properties and corrosion resistance at both high and low temperatures
– Good solderability and correct workmanship
– Cost effective compared to super duplex stainless steel
