General Information
Ti 230 combines the formability and weldability of unalloyed titanium with improved mechanical properties, particularly at elevated temperatures (up to 662°F (350°C)). The alloy may be used in the annealed condition as sheet, forgings and extrusions; it is used both in the airframe and in components such as bypass ducts for gas-turbine engines. Ageing can be used to raise the room temperature tensile properties by ~25% and nearly double the elevated temperature properties (eg creep @ 392°F(200°C)). Such a material is particularly attractive since it can be formed in the soft condition, thus lowering fabrication costs.
