Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. S500QL stahl, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.
In March, the global crude steel output outside China fell by 11.89% to 68.08 million tons, the highest decline since 2009. Among the major steel producing regions, the EU led the decline, followed by India, Japan, South Korea and the United States. In the first quarter, the global S500QL stahl, crude steel output outside China was 209 million tons, down 4.29% year on year.
