Our quality control department will do inspection for details of the steel materials S690QL steel equivalent to grade 50 before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

The toughness of steel such as S690QL steel equivalent to grade 50 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.

Medium thick plate refers to the steel plate with a thickness of 4.5-25.0mm. Those with a thickness of 25.0-100.0mm are called thick plates, and those with a thickness of more than 100.0mm are extra thick plates. Medium thick plate S690QL steel equivalent to grade 50 is a kind of flat steel with large width thickness ratio and surface area. The main materials of medium thick plate are Q235, Q345, S355JR, etc. The company not only provides raw steel materials, but also provides cutting and so on processing services for medium and thick plates, extra thick plates and wide and thick plates.
