Low alloy steel plate, refers to the steel plate whose alloy content is less than 3.5%. The most popular low alloy steel plate is CCS F32 hull steel plate, Q345B plate and its equivalent materials such as S355JR, A572 grade 50 and so on. Low alloy steel plate plays an important role in the construction, it must have enough strength and stability to bear the safety of the house. Low alloy steel plate is often used in large buildings with large bearing capacity and good cross-section stability, such as bridges, ships, lifting and transportation machinery, etc.
The main difference between CCS F32 hull steel plate, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.
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 CCS F32 hull steel plate 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 CCS F32 hull steel plate 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.
