Principal Design Features		This is an alpha-beta alloy generally selected for its high strength, fracture toughness and intermediate creep strength. Not generally available at the distributor level, it is widely available from producers in bar, billet, sheet and plate. Beta Transus (F +/- 25) 1780

Applications		Typical applications include airframe and jet engine components.

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

Welding		Rated as" limited" in terms of weldability.

Forging		Rough forge at 1650-1750 F, finish at 1600-1700 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 alloy are similar to those found in 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 recommended to reattain maximum performance characteristics.

Annealing		Soak at 1300-1500 F for 2 hours, air cool.
