Grade AH32/AH36, marine grade KD32 hull steel plate, 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.
What are the characteristics of medium and thick plate, marine grade KD32 hull steel plate? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, marine grade KD32 hull steel plate is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in marine grade KD32 hull steel plate etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
