Q345C is a steel grade, compared with Q345A,B, The low temperature impulse impact test has good performance. Contain harmful substance P, S quantity is lower than Q345A,B. The market price is higher than Q345A and B.
This is the distinction of rank, which represents the main impact of the temperature difference:
Grade Q345A, is not to do the impact;
Grade Q345B, is 20 degrees of room temperature impact;
Grade Q345C, is 0 degree impact;
Grade Q345D, is-20 degrees Chong;
Grade Q345E, is-40 degree impact.
At different impact temperatures, the impact value is also different. In the plate, is a low alloy series. In low alloy materials, this material is the most common.
