In recent years, with the wide application of Q345R steel plate, Katalor has improved the safety of Q345R steel plate. Steel plate is the main material for manufacturing pressure vessels. The quality of Q345R steel plate is the key factor to ensure the normal operation of the construction industry.
Compared with the conventional rolling process, controlling the rolling process of Q345R steel plate can effectively refine the grain and improve the strength of Q345R steel plate. In the same composition system, using the control Q345R steel plate rolling process can reduce the amount of alloy, reduce the cost. After the normalizing treatment of Q345R steel plate, the grain size of Q345R steel plate increased with the increase of heating temperature and holding time, the bending strength and tensile strength of Q345R steel plate decreased obviously, the yield ratio decreased, the elongation and impact performance increased.
Q345R steel plate has good comprehensive mechanical and technological properties. Q345R steel plate is the most widely used pressure vessel steel plate in China. Katalor can provide high quality service for Q345R steel plate. If you are interested in Q345R steel plate, please feel free to contact us. We will reply you as soon as possible.
