Titanium Alloy Tubing, Seamless, Hydraulic, 3Al - 2.5V, Texture Controlled, Cold Worked, Stress Relieved
This specification covers a titanium alloy in the form of seamless tubing.
AMS4946D results from a Five Year Review and update of this specification and includes a reduction in hydrogen content (Table 1), changes in furnace class and instrumentation requirements (3.3.1), use of vacuum/inert gas furnaces (3.3.2), reduced flarability sampling (4.3.3), allows cracking on interior surfaces of flattening specimens at high strain areas, corrects errors in T flattening factors (Table 3) and revised reporting.
