China's production of titanium and titanium sheet price newly developed applications of titanium alloys in recent years and more, but many no national standards, such as TA8, TA8-1, TA9-1, TA11, TA15, TA17, TA18, TB5, TB6, TB8, TC4ELI individual plants agreements were signed within the different users, is not conducive to marketing applications. So the urgent need for national standards GB / T3621-94 be amended to add new brands. Titanium and titanium alloy plate products in large quantity mainly by GB / T3621-94, In recent years, with the expansion of foreign demand for China-made equipment, and international trade, the user with the foreign standard ASTM B265 standard orders is increasing. But in terms of chemical composition, mechanical properties, process performance to the test method titanium wires there are differences between the two standards, especially large titanium sheet, composition and performance differences. We need to be adjusted to suit the needs of the market.
