Q345QDNH steel plate is a steel plate specially used for erecting railway or highway bridges. Q345QDNH steel plates are required to have high strength, toughness, and to withstand the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance.
Q345QDNH steel plate should also have good welding performance and low notch sensitivity. The difference between C, D, and E refers to the difference in impact temperature in their performance. They are: Q345QC level, which is 0 degree impact; Q345QD level, is -20 degree impact; Q345QE level, is -40 degree impact. At different impact temperatures, the value of the impact is also different.
