Principal Design Features		This near alpha alloy was created primarily to resist creep up to 805 F. It possesses the highest tensile strength and lowest density of any of the titanium alloys. It is available at the mill in bar, billet, plate, sheet, strip, extrusions and wire. Beta Transus (F +/- 25) 1900.

Applications		Found primarily in jet engine applications such as forged fan and compressor blades.

Machinability		As a family, titanium and its alloys have developed a mystique as a nightmare to machine. This is simply not the case. Experienced operators have compared its characteristics to those found in 316 stainless steel. Recommended practice includes high coolant flow(to offset the material's low thermal conductivity), slow speeds and relatively high feed rates. Tooling should be tungsten carbide designations C1-C4 or cobalt type high speed tools.

Forming		This alloy may be hot or cold formed. Popular methods include hydropress, stretch or drop-hammer. This material responds similarly to 300 series stainless steels.

Welding		Rated as "fair in terms of weldability.

Forging		Rough at 1010-1038 C(1850-1900 F), finish at 1010 C(1850 F).

Hot Working		Hot forming will reduce both the springback and required forming forces, and will increase the overall ductility of the material.

Cold Working		The cold working characteristics of this material are similar to those of austenitic stainless steels. In multiple forming operations, intermediate stress relieving is recommended to offset the alloy's tendency to work harden. Post-work annealing is required to re-attain optimum performance characteristics.

Annealing		Single--Hold at 738 C(1450 F) for 8 hours, furnace cool. Duplex--Perform single annealing plus heat to 788 C(1450 F) for 1/4 hour and air cool.(For bars and forgings, heat to 900 C(1670 F) for 1 hour and water or air quench, plus 593 C(1100 F) for 8 hours, air cool.) For Stress relief annealing, hold at 593-649 C(1100-1200 F) for 1 hour and air cool.
