The biggest impact of the new GB/T 1591 2018 release is Q345B , because the output of

Grade Q345 Imported Tube does not conform to grade S355

Hardness before forming Q345 was 80 Rockwell B, similar to the locally supplied tube, but when drawn down it increased to 97 while the locally supplied steel increased to only 90. This indicates that the Q345 becomes a much harder material when manipulated if compared to locally manufactured tube.Q345D,Q345D PLATE,Q345D STEELGB/T1591 Q345D steel shall be done charpy V notch impacting test under minus 20 centigrade.Many container manufacturers adpots these high tension strength to make offshore containers which can be used in deep oceans.Q345R Pressure Vessel Steel Plate for Boiler ManufactureQ345R Steel Introduction:.
