Material Notes:
Description: Research carried out these last five years has shown that combined additions of chromium, tungsten, molybdenum, nitrogen and copper, make it possible to design a super-austenitic stainless steel with mechanical properties equivalent to the alloy 625 and with very high corrosion resistance properties. Due to 22% Ni and 0.4% N additions, the new URANUS® B66 (UR B66) alloy exhibits a very stable microstructure, less prone to intermetallic phase precipitations than the other highly alloyed austenitic stainless steels. The UR B66 alloy has improved corrosion resistance properties compared to 6 Mo grades particularly in sea water and chlorinated sea water. Due to the optimum "cocktail" of alloying elements, the grade can be used in most very severe corrosive environments where it behaves almost equivalent or better than alloy 625.Information provided by manufacturer.
