<P>PROBLEM TO BE SOLVED: To provide β titanium alloy which has excellent cold workability, tensile strength and fatigue strength compared with those of the conventional one by mainly adjusting componential elements. <P>SOLUTION: The β titanium alloy contains, by mass, >0.2 to 3.0% N, 1.0 to 22.0% Cr and 0.05 to 0.15% O, and the balance Ti with inevitable impurities. The titanium alloy may further contains, by mass%, 0.5 to 5.0% Fe. Further, the titanium alloy may contains, by mass, 0.5 to 5.0% Sn. Further, the titanium alloy may contains, by mass%, ≤6.5% Al. <P>COPYRIGHT: (C)2012,JPO&INPIT |
