General Information

Principal Design Features

This is the most commonly used and widely available grade of unalloyed titanium. The grade combines excellent corrosion resistance and weldability with good strength, ductility and formability. Beta Transus (F +/- 25) 1675.


Applications

Chemical processing and marine equipment as well as a variety of airframe 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 coolan


Forming

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


Corrosion Resistance

Highly resistant to a wide variety of oxidizing and mildly reducing environments, including chlorides.


Welding

Rated as "good" in terms of weldability.


Heat Treatment

Not hardenable by heat treatment.


Forging

Roughing operations can begin at 899 C (1650 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 an


Annealing

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.


Other Physical Props
