Effect of grain size on yield strength ratio of SM490A carbon steel plate sheet

Ultrasonic flaw detection emits ultrasonic waves to the SM490A carbon steel plate sheet steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the SM490A carbon steel plate sheet steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.Q345qD bridge steel plate stock list: Q345qD size (mm) 14*2680*10100, 14*1230*6300, 10*1800*14000, 16*2200*11300, 16*2200*11400, 16*2200*11600, 21.5*2440*12900, 64*2000*10000, 10*1500*7050, 30*2300*5700, 16*2200*12000, 25*2200*6800, 21.5*2440*4750, 30*2300*5800, 16*2200*10800, 12*2440*4850, 21.5*2440*4600, 25*3100*9400, 1, 30*2200*5050.For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing.
