Corrosion Behavior of 2205 Duplex Stainless Steel in Bittern

Accordding to the actual process of salt making,the corrosion behaviors of 2205 duplex stainless steel in bittern solutions with different CO2-3 concentrations,S2- concentrations,pH values and flow velocities were studied by single factor experiment,uniform experiment and electro chemical test.The results showed that S2- concentration and pH value had great influences on corrosion resistance of 2205DSS in bittern,and CO2-3 concentration and flow rate had little influence.
