Product Code:SAE AMS4935
Title:Titanium Alloy Extrusions and Flash Welded Rings, 6Al - 4V, Annealed, Beta Processed
Issuing Committee:Ams G Titanium And Refractory Metals Committee
Scope:This specification covers a titanium alloy in the form of extruded bars and shapes, flash welded rings, and stock for flash welded rings.These products have been used typically for parts that do not require heat treatment but require high mechanical properties in the annealed condition and for which processing above the beta transus is permissible, but usage is not limited to such applications. This alloy exhibits high strength-to-weight ratios up to 750 掳F (399 掳C).
