Q345qC-Z25 bridge steel plate grade analysis

Q345qC-Z25 steel plate is a bridge structural steel plate, and the implementation standard is GB/T 714.

Q represents the yield strength, 345 represents the min. yield strength value, the unit is MPa, q is the bridge, C quality grade, corresponding to the corresponding impact temperature and impact power value, Z is the Z-direction performance, that is, the thickness direction performance of the steel plate, Z25 is the Z-direction Performance Level Requirements.

Q345qC-Z25 steel plate can be hot rolled and normalized heat treatment, when it needs to provide mechanical properties, the large thickness must be normalized for delivery.
