ABSTRACT:
A method of improving the resistance of oil-well tubular products made of .alpha.-type or (.alpha.+.beta.)-type Ti-based alloys to corrosion in a deep-well environment at high temperatures is disclosed. The method is characterized by adding, as an alloying element, (A) at least one platinum group metal in an amount of 0.02-0.20% by weight, or (B) at least one platinum group metal in an amount of 0.005-0.12% by weight and optionally at least one of Ni, Co, W, and Mo in an amount of 0.05-2.00% by weight.
