Principal Design Features		This unalloyed grade offers slightly higher mechanicals when compared with Commercially Pure Grade 2 while displaying similar ductility and formability. Distributor availability of Grade 3 is a fact to be considered here, as it is less widely used than Grade 2. Beta Transus (F +/- 25) 1690.

Applications		Generally used where corrosion resistance is a major design factor in chemical production components, marine and airframe applications.

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		Beta Transus (F +/- 25) 1900

Heat Treatment		Not hardenable by heat treatment.

Forging		Roughing operations can begin at 907 C (1165 F),while finishing 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.
