<p>PROBLEM TO BE SOLVED: To provide a titanium plate having both strength and formability, and to provide a plate for plate-type heat exchanger using the same.SOLUTION: There is provided a titanium plate having a crystal grain structure which is anαphase, including Fe: 0.020 to 0.150 mass%, O: 0.020 to 0.150 mass%, C: 0.002 to 0.100 mass%, and the balance titanium with inevitable impurities. A sum of contents of the Fe and the O (mass%) is 0.80 times or more the content (mass%) of the O, and a concentration of O in a crystal grain boundary is 1.0 mass% or more.</p> |
