Shipbuilding steel plates are used to manufacture marine and inland ship hulls, which require high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. BBN steel company produces various grades steel plates for shipbuilding like AH32, AH36, AH40, DH32, DH36, EH32, EH36, RF 32 HR ship plate and can produce marine steel plates and sheets with different certificates according to client needs.
With the continuous development of foreign business, our company has achieved pleasant cooperation with a number of freight companies, including international air transport (including international express) and sea bulk cargo, we can provide the best service. In order to better develop the air transport from mainland to foreign countries, so that the goods can be transferred in Hong Kong in a timely manner.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched RF 32 HR ship plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of RF 32 HR ship plate during tempering, while tempering determines the performance and life of the workpiece.
After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, RF 32 HR ship plate tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of RF 32 HR ship plate steel and 542,000 tons of steel.
