6mm thick SM520B carbon steel plate sheet stock resources

Grade AH32/AH36, SM520B carbon steel plate sheet, Grade DH32/DH36 high-strength structural steel products for hulls have good comprehensive mechanical properties, welding performance, good processing performance. Grade AH32/AH36 hull strucural steel is suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities, etc. in ocean, coastal and inland navigation areas.

Bridge steel plate is specially used for erecting railway or highway bridges. SM520B carbon steel plate sheet, bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.

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 SM520B carbon steel plate sheet 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 SM520B carbon steel plate sheet 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.
