Marine steel plates are classified as medium-thick plates, hot-rolled steel plates used for manufacturing hull structures produced in accordance with the requirements of the classification society. First, the toughness of the marine steel ABS Grade A, hull of ships use CCS DH40 plate, ABS EH36 plate is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.
BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of hull of ships use CCS DH40 plate steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main hull of ships use CCS DH40 plate production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the hull of ships use CCS DH40 plate steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
Our hull of ships use CCS DH40 plate, hot rolled mild steel sheets offer excellent corrosion resistance property in the server’s environments. The mild steel sheets provide high resistance to nitric and chloride corrosion in sulfide solutions. These SA283 GrC carbon stel plates offer high strength, tensile, yield, mechanical strength, ductility, hardness, toughness, etc. Mild steel sheet is worked very easily in a high-temperature application and show excellent resistance to chloride crossing and cracking stress.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
