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 EN 10025-6 S690QL properties 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.

The wear-resistant plate EN 10025-6 S690QL properties shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and EN 10025-6 S690QL properties hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the EN 10025-6 S690QL properties rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of EN 10025-6 S690QL properties steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
