Titanium Grade 7 is mechanically and physically equivalent to CP grade 2, but with the addition of palladium. The addition of palladium gives grade 7 enhanced crevice corrosion resistance at low temperatures and high PH and is the most corrosion resistant of all titanium alloys.

Principal Design Features

 

The most corrosion resistant of all currently available titanium alloys, this grade is especially well suited to applications requiring resistance to general as well as localized crevice corrosion. Grade 7 also exhibits good strength, welding and forming characteristics. The alloy is generally not available in the US distributor network, however producer availability is excellent. Beta Transus (F +/- 25) 1675.

 

 

Applications

 

Generally found in chemical process and production equipment 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

 

May be hot or cold formed using hydropress, power brake, stretch or drop hammer methods. Similar in characteristics to 300 series stainless steels.

 

 

Welding

 

Rated as "good" in terms of weldability.

 

 

Forging

 

Rough work can be performed at 900 C (1650 F), while finishing operations should be performed 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 work characteristics of this material is similar to that of a moderately tempered austenitic stainless steel. In multiple cold forming operations, intermediate stress relief is recommended to prevent tearing or other material damage. Post-work annealing is required to reattain optimum performance characteristics.

 

 

Annealing

 

Heat to 704 C (1300 F),hold for 2 hours follow by air cooling. For intermediate stress relieving, heat to 482-538 C(900-1000 F) and hold for 45 minutes.
