A detailed introduction to Q345 grade

Q345 can be divided into Q345A, Q345B, Q345C, Q345D and Q345E according to the grade. What they represent is that the temperature of the impact is different.

Q345A level, is not to impact;

Q345B grade, 20 degrees normal temperature impact;

Q345C, which is 0 degree impact;

Q345D level, which is-20 degree impact;

Q345E, which is-40 degree impact.

At different impact temperatures, the impact value is also different.
