On June 16, the 6-brand shipbuilding titanium alloy standard parts localization project of AVIC adopted the technical review jointly conducted by the Institute of Metal Research, the main use unit and the design unit of the Chinese Academy of Sciences, which means that the company has gone through six years of research and development. The formation of the new marine titanium alloy standard parts process plan and process summary obtained the "can be invested in the production of physical products" approval order. Marine titanium alloy standard parts have the characteristics of large size, high locking force and high shear resistance, especially the requirements of corrosion resistance, exceeding the technical standards of aviation fasteners. As the research unit of China's marine titanium alloy new fasteners, the 18 marine titanium alloy products that the aviation standard company passed the process review are based on the long-term development of aviation titanium alloy standard parts. The phased results of the process exploration of domestic titanium alloy materials. On June 16th, at the process evaluation meeting of domestic titanium alloy marine standard parts held in Guiyang, the review team listened to the report of the new work process plan and process summary of the navigation mark company, reviewed all the development process materials, and reviewed the processing and inspection. At the scene, it was agreed that the process plan of the six standard domestic titanium alloy materials for marine standard parts of the navigation mark company can pass the review and the production process of the physical product can be started.
