Grade 16 titanium alloy round bar is an unalloyed titanium with 0.04% to 0.08% palladium (Pd) added to its chemical composition, maintaining standard oxygen levels. This alloy is renowned for its excellent corrosion resistance and mechanical properties, making it suitable for high-temperature and corrosive environments, such as petrochemical equipment and aerospace components. The standard sources for Grade 16 titanium alloy include the ASTM B265 and GB/T 3620 series standards. ASTM B265 is a standard established by the American Society for Testing and Materials (ASTM), which specifies the chemical composition, mechanical properties, and application range of Grade 16 titanium alloy, [4][11]. The GB/T 3620 series standard is a Chinese national standard that covers the design, chemical composition, naming rules, and other aspects of titanium and titanium alloys, with TA17 corresponding to Grade 16 in ASTM B265.
