Mechanical property requirements.

Diameter or thickness, inches Tensile Strength (min), psi Yield Strength (min), psi Elongation, (min) % Reduction in area* (min), %
< 1.75 125,000 115,000 10 25
< 1.75 125,000 113,000 10 20

Mechanical Properties

The microstructure must show fine dispersion of alpha and beta phases in accordance with ASTM F136.
No alpha case may be visible at a magnification of 100x.
The beta temperature must be determined with a suitable method and reported for each heat lot on the material certification.
Straightness of material should be equal to or tighter than the straightness tolerance specified in ASTM B348-13. Maximum straightness allowed for titanium bars is displayed below in Table.
