Abstract:
Disclosed is a titanium or titanium alloy plate rolled in one direction, wherein a lubricating film is coated on the surface and the coefficient of sliding friction of the lubricating film-coated surface is controlled to less than 0.15. The elongation (L-El) of the titanium or titanium alloy plate in the rolling direction and the r value (T-r) in the direction perpendicular to the rolling direction have the following relation (1). (T-r)/(L-El)≧0.07 (1)
