In recent years, in line with the development trend of iron and A709 grade 50W bridge steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A709 grade 50W bridge steel plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and A709 grade 50W bridge steel plate steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and A709 grade 50W bridge steel plate medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous A709 grade 50W bridge steel plate pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
As to the Chemical composition, the different content is a main on carbon content, while the carbon content of A709 grade 50W bridge steel plate, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 grade D is 230MPa (33 ksi).
The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.
