Titanium Commercially Pure Grade 1

Annealing Procedure

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

Applications

Corrosion resistant applications in the chemical process industry, airframe and other areas where ease of formability is required.

Cold Workability

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.

Forgeability

Rough work at 871 C (1600 F), finish at 788-843 C (1450-1550 F)

Formability

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

Heat Treatability

Not hardenable by heat treatment.

Hot Workability

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

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.
