Grade A ship steel is mainly used for the internal frame of the ship and the outer plate bearing general stress. Grade B, Grade D and Grade E ship steel can be used for important structures in high stress areas such as hull outer plate and main deck. The Grade E ship steel has good low temperature performance, which is suitable for the hull outer plate, deck, etc. According to the minimum yield strength, the high-strength ship steel is divided into four grades: A, D, E and F. The commonly used high strength ship steels are AH32, DH32, EH32, etc.
CCS AH40 high tensile steel plate,The main difference between , 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 045 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,CCS AH40 high tensile steel plate.
CCS AH40 high tensile steel plate,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 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℃.
