EN 10083-3 51CrV4 alloy steel plate BBN steel annual capacity 200,000tons
Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of EN 10083-3 51CrV4 alloy steel plate service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
Cold rolled coil products EN 10083-3 51CrV4 alloy steel plate have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products EN 10083-3 51CrV4 alloy steel plate is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils EN 10083-3 51CrV4 alloy steel plate with different surface roughness can be produced (glossy surface or matte surface, etc.).
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.
There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than EN 10083-3 51CrV4 alloy steel plate, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.
