If the thickness of Q345D structure steel plate is above 70mm, the risk of non preheating is very large. The impurity S and P content of GB/T 1591 Q345D steel plates are low, so the low temperature impact performance of Q345D steel is good. From the welding point of view, less impurity elements of the parent material is beneficial to control the welding hot crack. Of course, since the parent material chooses Q345D material, The effect of shot peening on fatigue life of Q345D T q345d steel for welded structure materialNov 01, 2016 · Shot peening (SP) is an efficient mechanical surface treatment to improve the fatigue property of metallic component.
