Low Temp Elongation Properties for Titanium (Grade 2)

[geirkvaale]

Hi,

I am looking for the low temp elongation properties for Titanium (Grade 2 - unalloyed - "comercially pure")

In room temp the mimimum elongation value is 20% (for seamless pipe according to ASME B861), but how does it change at lower temperatures?

Anybody konws? Hope somebody can help me. Have googled it for hours without finding anything...

Look on the Timet website.

LOW TEMPERATURES
Titanium has excellent properties at low temperatures. As was discussed in the Mechanical Properties section, best ductility at very low temperatures is available from TIMETAL 35A (Gr.1) and TIMETAL 50A (Gr.2). However, no marked drop in impact resistance is observed at subzero temperatures in any of the titanium alloys. Because of this, the ASME Boiler and Pressure Vessel Code allows unalloyed titanium TIMETAL 35A (Gr.1), TIMETAL 50A (Gr.2), TIMETAL 65A (Gr.3) and TIMETAL 50A Pd (Gr.7) to be used down to -75 degrees F. provided the user satisfies himself that suitable ductility is available at the design temperature. Notched and unnotched tensile tests are suggested by ASME as means whereby the titanium alloy can be judged to be suitable.
