BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, BV grade D refrigerated cargo ship steel plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.
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, BV grade D refrigerated cargo ship steel, ABS EH36 plate is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.
Tempering the important BV grade D refrigerated cargo ship steel welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve BV grade D refrigerated cargo ship steel strength, plasticity and toughness.
With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.
