ABSTRACT:
A method for producing a titanium strip having a small proof strength anisotropy and an improved ductility comprises the steps of: reheating a hot rolled titanium strip containing 0.1% by weight or less of oxygen and 0.1 to 0.5% by weight of iron at a .beta. region temperature and cooling by water, aging the obtained titanium strip at a temperature of 200.degree. to 500.degree. C. for 30 minutes or more, cold rolling the titanium strip at a rolling reduction of 30% or more; and, annealing the cold rolled titanium strip at a temperature of 600.degree. to 800.degree. C.
