A comparison of the properties of duplex steels SAF2205, SAF2507, and austenitic steel 2RE69 (2522). Currently, the duplex steels used in the manufacturing of equipment by the fertilizer industry include SAF2205, among others. There are reports indicating that SAF2205 is used for the heat exchange tubes in the high-pressure ammonium methanate condensers at Lutianhua, and it is said to perform well. However, the current designs still mostly use 2RE69. I would like to know what the differences are between these two materials in terms of corrosion resistance, mechanical properties, and weldability. Does anyone know? Please advise.
