Abstract:The Chinese National Standard (GB) system of titanium and titanium alloy from the establishment and development of three major changing stages was reviewed, and the important changes in the system and improvement situation in Chinese Titanium GB, in specialty, the important changes since 2007 years. including the development of new designations, adoption of international practices in chemical composition and mechanical property, perfection of basic standards and testing methods for the standard system, about 10 test method standards were constituted and revised. The international practices in part of the performance test methods, establishment of new classificatory product standard, including ingot, halftone, welded tube, extrusion tube and titanium scraps, etc were adopted. The international and foreign advanced titanium standards system reaching international advanced level were compared, and further improvement ideas and suggestions on Chinese titanium standards system development: heighten standard cognizing degree to achieve international currency; quicken standardization of new developed designations to promote new alloys application; strengthen constituting method standards were proposed to make Chinese titanium standard system more perfect.
