High yield strength RINA DH40 hull steel plates specifications

09CuPCrNi-A steel belongs to weathering steel. Through alloying of Cu, Mn, Si, Al and simply adjusting part of element content of ordinary low carbon steel (Q235 steel), economic weathering RINA DH40 hull steel plates steel with good atmospheric corrosion resistance and comprehensive mechanical properties can be produced without changing the production process of Q235 steel. 09CuPCrNi-A steel is mainly used for railway, vehicle, bridge, tower and other steel structures exposed to the atmosphere for a long time.

Different form RINA DH40 hull steel plates, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

S355J2 steel plate RINA DH40 hull steel plates 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 RINA DH40 hull steel plates 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℃.

We have a professional production team and high-quality production equipment, and we also have a great RINA DH40 hull steel plates advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the RINA DH40 hull steel plates production of high-quality steel plates, steel pipes and other products that meet customer requirements.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, RINA DH40 hull steel plates sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
