Description

Titanium UNS R54620 is a two-phase, Alpha Beta Alloy. It is usually used in the annealed or solution treated and aged conditions. It’s a heat treatable, high strength alloy with lower toughness and ductility than Titanium Grade 5 (6Al-4V) and it’s difficult to weld. Cold forming of UNS R54620 is difficult because of its high strength. This grade can be welded by the inert gas shielded, fusion welding process but the heat effected area will have less ductility and toughness than the parent material. This grade is primarily used for airframe and jet engine parts, rocket engine cases and ordinance components.
