Machinability
Grade 6Al 6V 2Sn titanium alloy can be machined using slow speeds, right quantity of coolant flow and high feed rates. High-speed tools should be used for tooling this alloy and the recommended tool types are tungsten carbide designations C1-C4 or cobalt based.
Forming
Grade 6Al 6V 2Sn titanium alloy can be hot or cold formed. Forming techniques include hydropress, stretch or drop-hammer.
Welding
Welding of grade 6Al 6V 2Sn titanium alloy should be performed at beta transus (F +/- 25) 1735.
Heat Treatment
The material can be solution treated at 843-913°C (1550-1675°F) for 1 h, and then water cooled.
Annealing
For annealing grade 6Al 6V 2Sn titanium alloy, the material has to be held at 704°C (1300°F) for 2 h, and air cooled. If stress relieving is required, the material has to be held at 593°C (1100°F) for 2 h and air cooled.
Forging
Rough forging can be performed at 932°C (1710°F), and completed at 843°C (1550°F).
Hot Working
Hot working enhances the overall ductility of the material.
Cold Working
Cold working features of this material is same as that of austenitic stainless steel. Post-work annealing is recommended to re-attain favorable performance properties.
Aging
