What is the performance of Q345E steel plate

The stamping property of Q345E steel plate refers to the property that Q345E steel is deformed by stamping without crack and other defects. Many metal products are made by stamping process. In order to ensure the quality of products and the smooth progress of technology, Q345E steel plate used for stamping must have qualified stamping performance.

The weldability of Q345E steel plate refers to the weldability of Q345E steel to achieve the expected quality requirements through common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties in the weld area.

Q345E steel plate can withstand bending without fracture at room temperature, which is called cold bending. The greater the bending degree can bear before the crack appears, the better the cold bending performance of the material.

The heating treatment of Q345E steel plate means a process operation to get the required performance through certain heating, heat preservation and cooling methods to change the internal structure of Q345E steel.
