A sheet, a plate, a bar or wire is made of Ti and has high ductility and low
material
anistropy in a plane of a sheet or plate, or in a sectional plane of a bar or a
wire and contains Fe, in mass, at 0.15-0.5%, N at 0.015-0.041 and 0, with the balance
Ti and unavoidable impurities. When the Fe content is defined as [Fe], the N content
as [N] and the 0 content as [0], the oxygen equivalent value
