APPLICATIONS/ENVIRONMENTS/DESIGN CONSIDERATIONS

Chemical and petrolchemical indusrty, environments containing chlorides, offshore and onshore applications, extraction of oil and gas from sour wells. The high strength of 2205 DSS makes the material an attractive alternative to the austenitic steels in structures subjected to heavy loads.
