06Ni9DR is -196℃ grade low temperature pressure vessel steel plate. With its good low-temperature impact resistance and extremely low thermal deformation coefficient, it is widely used in LNG ships and LNG storage and transportation projects. Generally called 9Ni or 9-nickel steel, the corresponding foreign brands are SA553, SA353, and 9Ni.
