<p>Provided are a titanium sheet which combines strength with formability and a plate for plate heat exchangers which was obtained from the titanium sheet. The titanium sheet has a crystal grain structure which comprises anαphase, and is characterized by containing 0.020-0.150 mass% Fe, 0.020-0.150 mass% O, and 0.002-0.100 mass% C, with the remainder comprising titanium and unavoidable impurities. The sheet is further characterized in that the sum of the contents (mass%) of the Fe and the C is at least 0.80 times the content (mass%) of the O and the concentration of C in the grain boundaries is 1.0 mass% or higher.</p> |
