Principal Design Features		This alpha-beta alloy can be heat treated to higher strengths and heavier section sizes than alloy 6AL-4V. It combines excellent strength, corrosion resistance and moderately good fabricability. Beta Transus (F +/- 25) 1735.

Applications		Used primarily in plate and forging applications for airframe sections, rocket cases and ordnance 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		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		Beta Transus (F +/- 25) 1735

Heat Treatment		Solution treat at 843-913 C(1550-1675 F) for 1 hour and water cool.

Forging		Rough at 932 C(1710 F), finish at 843 C(1550 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		Hold at 704 C(1300 F) for 2 hours, air cool. For stress relieving, hold at 593 C(1100 F) for 2 hours and air cool.

Aging		Age at 538-621 C(1000-1150 F) for 4-8 hours and air cool.
