• Comparison with 316L and 317L Austenitic Stainless Steel
  
  The 2205 duplex stainless steel alloy outperforms 316L and 317L austenitic stainless steels in terms of resistance to pitting and crevice corrosion. It exhibits superior corrosion resistance.
  
  
• Thermal Properties
  
  Compared to austenitic stainless steels, the 2205 alloy has a lower coefficient of thermal expansion and a higher thermal conductivity.
  
  
• Strength and Weight
  
  Duplex 2205 alloy boasts twice the compressive strength of austenitic stainless steels. This allows designers to reduce its weight when compared to 316L and 317L.
  
  
• Temperature Range
  
  The 2205 alloy is particularly suitable for use in the temperature range of -50°F to +600°F. For applications with strict requirements, especially welded structures, it can also be used at lower temperatures.
