2 inch S500QL equivalent heavy plate spot

The toughness of steel such as S500QL equivalent is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

Q345 is a grade of carbon structural steel. Q is the meaning of yield strength, which S500QL equivalent is taken from the initial of Chinese Pinyin of "Qu"; 345 is the value of yield point, in MPa. Q345 refers to carbon structural steel with yield point (σ s) of 345mpa. The following letters indicate the quality level, including A, B, C, D and E. Q345 steel has good comprehensive mechanical properties, low temperature performance, good plasticity and weldability. Q345 steel is usually in hot rolling or normalizing state.

What are the characteristics of medium and thick plate, S500QL equivalent? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, S500QL equivalent is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
