The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel A709 grade 50W high strength steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the A709 grade 50W high strength steel market and has strong competitiveness.
SA516Gr60 material, SA516Gr70, SA516Gr60N, SA516Gr70N steel plate in thickness ≤1.5in (40mm) is usually supplied in rolled state. The plate can also be ordered according to normalizing or stress relief, or normalizing plus stress relief. SA516Gr60 steel plate when thickness> 1.5in. (40mm) should be normalized. Unless otherwise specified by the customer, A709 grade 50W high strength steel, SA516Gr60 steel plate (thickness ≤40mm) should be normalized when there is a notch toughness requirement.
A709 grade 50W high strength steel, Wear-resistant steel plate has good connection performance:The base material of the wear-resistant steel plate is ordinary Q235 steel plate, which ensures the toughness and plasticity of the wear-resistant steel plate, and provides strength against external forces. Wear-resistant steel plate can be connected with other structures by various methods such as welding, plug welding, and bolt connection. The connection is firm, not easy to fall off, and the connection mode is more rich than other materials.
The research methods of isothermal treatment of A709 grade 50W high strength steel, wear-resistant plate include many excellent technologies, such as optical microscope, transmission electron microscope, X-ray diffractometer and electron backscatter diffraction technology. With the increase of annealing temperature, the proportion of ferrite in wear-resistant plate will gradually decrease, and bainite will increase, while the retained austenite will be distributed in ferrite grain boundary and crystal in elliptical and fine strip shape.
SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. A709 grade 50W high strength steel, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
