The comprehensive mechanical properties of BV grade A ferry steel plate, Q345B steel plate are good, the low temperature performance is acceptable, and the plasticity and weldability are good. Q345B steel is used for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads, mechanical parts, building structures, general metal structural parts. Plate Q345B is the most versatile and the most used pressure special steel plate for container.
Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and BV grade A ferry steel plate resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, BV grade A ferry steel plate new materials, and promotes the competition of enterprises Struggle.
Most common BV grade A ferry steel plate steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled BV grade A ferry steel plate steel plates.
When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the BV grade A ferry steel plate, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality BV grade A ferry steel plate products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
