Product Details:

China ASTM F51 S31803 (2205)  API 6BX Reducing RTJ Flange 


   

   Duplex stainless steel 2205 combine the best attributes of both austenitic and ferritic stainless steels and provide high strength/ductility with good corrosion resistance to corrosion (including stress corrosion cracking). This gives them a significant advantage over 316L and 317L stainless steels.
