Question:

Can 16Mn steel plate be used instead of Q345D steel plate?

Can 16Mn steel plate be used instead of Q345D steel plate?

Answer:

If the use of Q345D instead of using 16Mn, that can be, but 16Mn instead of Q345D can not, and also can not buy 16Mn steel now, that is the old number, and the latest brand is Q345A
16Mn steel plate is the old brand, the latest brand is Q345, but Q345D has a special requirement than 16Mn, that is, 20 degrees lower temperature test
16Mn steel plate, equivalent to Q345A steel plate, can not be replaced.
