Titanium or titanium alloy contacting surface

摘要

The invention essentially relates to the use of a substantially nickel free non-stainless low alloy steel, for manufacturing at least the surface of an item intended to be put into contact with titanium or a titanium alloy, as well as to a method for manufacturing at least the surface of such an article. The invention notably relates the use of this alloy for manufacturing at least the contact surface of a mold for hot forming titanium-based alloys or titanium alloy in the solid-state, or for manufacturing at least the contact surface of tools for densifying and forming bulk titanium alloys or titanium or titanium alloy powders. Items intended to be put in contact with titanium or a titanium alloy may be produced with the invention.
