Q345D alloy structural steel

Q345 is a steel material. Q345 steel is low carbon alloy steel.
Q345 steel has good comprehensive performance, good low temperature performance, good cold stamping performance, good welding performance and machinability.

Q355ND low-alloy steel plate, adding the letter N generally requires the steel to be delivered by normalizing!
