Grade Q345 Imported Tube does not conform to grade S355
The imported product is a Carbon Manganese steel while locally produced tube is typically produced with low Carbon micro-alloyed steel. Thus the Q345 has a much higher Carbon Equivalent content close to the maximum recommended maximum value of 0.45. Tests done on some of this material yielded the following chemistry, the table also Handbook of Comparative Handbook World Steel track of which comparison criteria were used for a given steel, each table within a chapter was sequentially numbered and appended with either the letter A or B. Table numbers ending in the letter A designate that the table was the main criterion used for comparison; whereas table numbers ending with the letter B were "mirrored" from the A table.
