How to improve the qualification rate of Q345B steel

In order to find out the unqualified reason of Q345B steel plate with 20 ~ 60mm specifications by ultrasonic testing, the microstructure and composition of unqualified parts of the plate were analyzed by means of metallographic scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results show that the main reasons for the unqualified flaw detection are the Q345 steel property and specification are equivalent to The Q345 is a steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities. This particular grade of steel is a general purpose manufacturing steel in construction equipment field.
