The A709 Gr 50W carbon steel plate plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The A709 Gr 50W carbon steel plate products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.
The company has strict control on the quality of A709 Gr 50W carbon steel plate. Each A709 Gr 50W carbon steel plate is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the A709 Gr 50W carbon steel plate meets the specified quality requirements. If the A709 Gr 50W carbon steel plate does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified A709 Gr 50W carbon steel plate shall be removed, marked, registered and effectively isolated; the A709 Gr 50W carbon steel plate shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.
A709 Gr 50W carbon steel plate and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of A709 Gr 50W carbon steel plate and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, A709 Gr 50W carbon steel plate.
