BBN steel extend the width of LR DH40 high strength steel plate

China's shipbuilding and navigation technology has a long history. As an LR DH40 steel supplier in the Republic of China, BBN Steel has been striving to meet the innovative technological development of large domestic shipyards, making outstanding contributions to the rapid development of China's shipbuilding steel industry.

BBN LR DH40 high strength steel plate has passed the certification of ABS, LR, CCS, RINA, DNV GL, BV, NK, KR and RMRS of the top ten classification societies in the world. BBN LR DH40 high strength steel plate quality and overall supply capacity reached the world's advanced level.

BBN steel continues to extend the width of LR DH40 high strength steel plate and the strength of shipbuilding steel. This greatly promoted the development of China's shipbuilding industry. The width of LR DH40 high strength steel plate can reach 4.6 meters by the 5 meter wide shipping grade steel plate production line.

The 5 meter wide ASTM A131 DH40 high strength steel plate production line effectively reduces the hull welds and provides convenience for hull structure design and optimization. At present, the production capacity of BBN Steel's ultimate specification is increasing continuously, and the thinnest thickness of LR DH40 high strength steel plate can reach 3mm.

BBN steel adopts temperature controlled rolling process, which greatly improves the weldability of LR DH40 high strength steel plate, and plays an irreplaceable role in improving hull safety and speeding up shipyard manufacturing cycle.
