Q345C H PROFILE BEAM

Q345C steel is Q345 grade C low alloy high strength steel. The low temperature impact test of Q345C material has a lower temperature and better performance, comparing with that of Q345A and Q345B steel. Besides, the content of harmful substances P and S is lower, and market price of Q345C steel is higher than that of Q345A and Q345B steel.
