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.
As we all know, China's steel production is the largest variety of rebar, followed by steel plate and sheet, and the largest percent of steel grade produced in the plate is Q235B, followed by Q345B. The biggest impact of the new GB/T 1591-2018 release is Q345B, because the output of other grades has little effect.
