About Q345B steel plate cutting

Flame cutting is one of the most common used cutting methods for Q345B steel plate. However, according to the introduction of professionals in this field, not all Q345B steel plates are suitable for flame cutting, because this cutting method has requirements on the thickness of Q345B steel plate. If the Q345B steel plate is relatively thin or its thickness is relatively small, then if flame cutting is carried out, the Q345B steel plate is prone to thermal deformation. Therefore, flame cutting method is more suitable for cutting thick Q345B steel plate.

Q345B steel plate cutting is generally carried out before painting the Q345B steel plate surface, especially the hot cutting of Q345B steel plate, because if the Q345B steel plate hot cutting is carried out after painting the Q345B steel plate, in the high temperature environment, the paint surface of the Q345B steel plate will appear scorching and other problems and produce peculiar smell, which will seriously damage the paint surface, which will affect the cutting quality of the Q345B steel plate.
