Mechanical Property and Processing Property of Titanium Bar

Titanium mechanical property

Titanium has good low temperature ductility, especially low levels of interstitial elements of α-type alloys suitable for use at low temperatures, such as a container for cryogenic rocket engine or on a manned spacecraft.

   Fatigue performance characteristics similar to steel, with obvious physical fatigue limit, repeated bending fatigue limit for titanium is 0.6 ~ 0.8Rm, fatigue properties of the titanium metal surface condition and the stress concentration factor is sensitive.

  Heat resistance of titanium is lower than nickel and iron more information on how it is different can be found at Titanium CN. The poor wear resistance of titanium can be impoved by nitriding, carbon, boron.

Titanium processing property

Titanium can be forged, rolling, extrusion, stamping, and other various processing pressures; steel heating devices can be used for titanium heating. furnace atmosphere required to maintain a neutral or weakly oxidizing atmosphere, heat will not allow the use of hydrogen.
The yield ratio of titanium (Rel / Rm) is 0.70 to 0.95, large deformation resistance; relatively low modulus of elasticity, that's why it is difficult for titanium in the molding process.
Titanium has good weldability, weld strength, ductility and corrosion resistance similar to the base material. To prevent contamination of welding, to adopt tungsten argon arc welding.
Titanium cut machining is more difficult. The main reason is titanium friction coefficient, poor thermal conductivity, the heat focused on the tip, so that the tip quickly soften; while the chemical activity of titanium high temperature easy to adhere to the tool, causing adhesive wear. When cutting, the correct selection of tool material should maintain Fengrui tool, and using good cooling.
